Decimal To Fraction Formula 

Decimal numbers are used to express quantities that are not necessarily whole numbers or integers. However, sometimes it is useful to convert a decimal number to a fraction, especially when dealing with ratios or proportions. A fraction is a way to represent a number as a ratio of two integers, where the first integer is called the numerator and the second integer is called the denominator. The denominator cannot be zero.

The formula to convert a decimal number to a fraction is as follows:

1. Write the decimal number as a fraction with the decimal number as the numerator and a denominator of 1. For example, if the decimal number is 0.75, write it as 0.75/1.
2. Multiply both the numerator and denominator by 10, 100, 1000, or any other power of 10, depending on the number of decimal places. For example, if the decimal number is 0.75, multiply both the numerator and denominator by 100 to get 75/100.
3. Simplify the resulting fraction by dividing both the numerator and denominator by their greatest common factor (GCF). For example, if the resulting fraction is 75/100, divide both the numerator and denominator by 25 to get 3/4, which is the simplified fraction.

In summary, to convert a decimal number to a fraction, we need to write the decimal number as a fraction, multiply both the numerator and denominator by a power of 10, and simplify the resulting fraction.

It is important to note that not all decimal numbers can be expressed as a fraction. For example, the decimal number 0.33333333… (where the 3s repeat infinitely) cannot be expressed as a fraction with integers in the numerator and denominator. Such numbers are called irrational numbers and cannot be expressed as a ratio of integers.

How Do You Turn 0.75 Into A Fraction? 

To turn the decimal number 0.75 into a fraction, we need to follow the formula for converting a decimal to a fraction:

1. Write the decimal number as a fraction with the decimal number as the numerator and a denominator of 1.

So, we write 0.75 as 0.75/1.

2. Multiply both the numerator and denominator by 10, 100, 1000, or any other power of 10, depending on the number of decimal places.

Since 0.75 has two decimal places, we need to multiply both the numerator and denominator by 100 to eliminate the decimal point. This gives us:

0.75/1 x 100/100 = 75/100

3. Simplify the resulting fraction by dividing both the numerator and denominator by their greatest common factor (GCF).

In this case, the greatest common factor of 75 and 100 is 25, so we can simplify the fraction by dividing both the numerator and denominator by 25:

75/100 ÷ 25/25 = 3/4

So, 0.75 can be expressed as the fraction 3/4.

To check if this is correct, we can divide the numerator by the denominator and see if it equals the original decimal:

3 ÷ 4 = 0.75

Since 0.75 is equal to 0.75, we have confirmed that our fraction is correct.

In summary, to turn a decimal like 0.75 into a fraction, we need to write the decimal as a fraction, multiply both the numerator and denominator by a power of 10 to eliminate the decimal point, and simplify the resulting fraction.

How Do I Convert A Decimal To A Mixed Fraction? 

To convert a decimal to a mixed fraction, we first need to convert the decimal to an improper fraction, and then we can convert the improper fraction to a mixed fraction. Here are the steps to follow:

1. Write the decimal as a fraction with a denominator of 1 followed by as many zeros as there are decimal places.

For example, if the decimal is 3.25, we write it as 3.25/1,000.

2. Simplify the fraction by dividing both the numerator and denominator by their greatest common factor (GCF).

In this case, the GCF of 3.25 and 1,000 is 25, so we can simplify the fraction by dividing both the numerator and denominator by 25:

3.25/1,000 ÷ 25/25 = 13/400

So, 3.25 can be expressed as the improper fraction 13/400.

3. Divide the numerator by the denominator to get the whole number part of the mixed fraction.

In this case, 13 ÷ 400 = 0 with a remainder of 13.

So, the whole number part of the mixed fraction is 0.

4. Write the remainder as the numerator of the fractional part of the mixed fraction and the denominator as the same as the denominator of the improper fraction.

In this case, the fractional part of the mixed fraction is 13/400.

So, the mixed fraction is 0 13/400.

Therefore, 3.25 is equivalent to the mixed fraction 0 13/400.

To check if this is correct, we can convert the mixed fraction back to a decimal:

0 13/400 = (0 x 400 + 13)/400 = 13/400 = 3.25/100

Since 3.25/100 is equal to 0.0325, which is the original decimal, we have confirmed that our mixed fraction is correct.

In summary, to convert a decimal to a mixed fraction, we need to first convert the decimal to an improper fraction, and then divide the numerator by the denominator to get the whole number part of the mixed fraction and write the remainder as the numerator of the fractional part of the mixed fraction.

What Is 0.375 As A Decimal Fraction?

0.375 is already a decimal fraction. However, we can also write it as a fraction in a simplified form.

To do this, we can use the formula for converting a decimal to a fraction:

1. Write the decimal number as a fraction with the decimal number as the numerator and a denominator of 1.

So, we write 0.375 as 0.375/1.

2. Multiply both the numerator and denominator by 10, 100, 1000, or any other power of 10, depending on the number of decimal places.

Since 0.375 has three decimal places, we need to multiply both the numerator and denominator by 1,000 to eliminate the decimal point. This gives us:

0.375/1 x 1,000/1,000 = 375/1,000

3. Simplify the resulting fraction by dividing both the numerator and denominator by their greatest common factor (GCF).

In this case, the greatest common factor of 375 and 1,000 is 125, so we can simplify the fraction by dividing both the numerator and denominator by 125:

375/1,000 ÷ 125/125 = 3/8

So, 0.375 can be expressed as the fraction 3/8.

Therefore, 0.375 as a decimal fraction is equivalent to the simplified fraction 3/8.

To check if this is correct, we can convert the fraction back to a decimal:

3/8 = 0.375

Since 0.375 is equal to 0.375, we have confirmed that our fraction is correct.

In summary, to write 0.375 as a decimal fraction, we can use the formula for converting a decimal to a fraction by writing the decimal as a fraction, multiplying both the numerator and denominator by a power of 10 to eliminate the decimal point, and simplifying the resulting fraction. We end up with the simplified fraction 3/8, which is equivalent to the original decimal 0.375.

2. Multiply both the numerator and denominator by 10, 100, 1000, or any other power of 10 depending on the number of decimal places.

In this case, since there are two decimal places, we will multiply both the numerator and denominator by 100:

0.75/1 x 100/100 = 75/100

3. Simplify the fraction by dividing both the numerator and denominator by their greatest common factor (GCF).

In this case, the GCF of 75 and 100 is 25, so we can simplify the fraction by dividing both the numerator and denominator by 25:

75/100 ÷ 25/25 = 3/4

So, 0.75 as an improper fraction is 3/4.

In summary, the steps to convert a decimal to an improper fraction are:

1. Write the decimal as a fraction with a denominator of 1 followed by as many zeros as there are decimal places.
2. Multiply both the numerator and denominator by a power of 10 depending on the number of decimal places.
3. Simplify the resulting fraction by dividing both the numerator and denominator by their greatest common factor.

How To Convert Fraction To Decimal Without Calculator?

Converting a fraction to a decimal without a calculator involves a few simple steps. Here’s how to do it:

1. Divide the numerator by the denominator.

For example, let’s say we want to convert the fraction 5/8 to a decimal. We would divide 5 by 8:

5 ÷ 8 = 0.625

So, 5/8 as a decimal is 0.625.

2. Simplify the fraction (if possible).

If the fraction is not already in its simplest form, simplify it before converting it to a decimal. To simplify a fraction, divide both the numerator and denominator by their greatest common factor (GCF). For example, to simplify the fraction 10/25:

• Find the GCF of 10 and 25, which is 5.
• Divide both the numerator and denominator by 5: 10/5 = 2 and 25/5 = 5.
• The simplified fraction is 2/5.

Now, we can convert the simplified fraction, 2/5, to a decimal:

2 ÷ 5 = 0.4

So, 2/5 as a decimal is 0.4.

3. Convert mixed numbers to improper fractions (if necessary).

If the fraction is a mixed number (a whole number and a fraction), convert it to an improper fraction before converting it to a decimal. To convert a mixed number to an improper fraction:

• Multiply the whole number by the denominator.
• Add the numerator to the result of step 1.
• Use the denominator from the mixed number as the denominator of the improper fraction.

For example, to convert the mixed number 2 1/3 to an improper fraction:

• Multiply 2 (the whole number) by 3 (the denominator): 2 × 3 = 6.
• Add the numerator (1) to the result of step 1: 6 + 1 = 7.
• Use the denominator (3) from the mixed number: the improper fraction is 7/3.

Now, we can convert the improper fraction, 7/3, to a decimal:

7 ÷ 3 = 2.333…

Note that in this case, the decimal is repeating. If you only need a certain number of decimal places, round the result accordingly.

In summary, to convert a fraction to a decimal without a calculator:

1. Divide the numerator by the denominator.
2. Simplify the fraction (if possible) by dividing both the numerator and denominator by their GCF.
3. Convert mixed numbers to improper fractions before converting them to decimals.

With these steps, you can easily convert any fraction to a decimal without a calculator.
