To convert a decimal number to a fraction, we need to understand the relationship between decimals and fractions. A decimal number is simply another way of representing a fraction with a denominator of 10, 100, 1000, and so on. For example, the decimal 0.5 is equivalent to the fraction 5/10, or 1/2. Similarly, the decimal 0.25 is equivalent to the fraction 25/100, or 1/4.

To convert the decimal number 1.25 to a fraction, we first need to recognize that it is made up of two parts: 1 and 0.25. The whole number part (1) is the same as the fraction 1/1. The decimal part (0.25) can be written as 25/100 or 1/4, as we saw earlier.

Now we have:

1.25 = 1 + 0.25

1.25 = 1 + 25/100

1.25 = 1 + 1/4

To combine these two fractions, we need to find a common denominator. The smallest common denominator of 1 and 4 is 4, so we can rewrite the whole number 1 as 4/4:

1.25 = 4/4 + 1/4

1.25 = (4+1)/4

1.25 = 5/4

Therefore, 1.25 as a fraction is 5/4.

1.25 as a fraction

In mathematics, a fraction is a way to represent a number as a ratio of two integers. A fraction consists of a numerator, which is the top number, and a denominator, which is the bottom number. To convert a decimal like 1.25 to a fraction, we can use some simple steps.

Step 1: Identify the decimal as a fraction over 1.

In this case, we have 1.25, which can be written as 1.25/1.

Step 2: Multiply the numerator and denominator by a power of 10 to eliminate the decimal.

Since we have one digit after the decimal point, we can multiply both the numerator and denominator by 10. This gives us 1.25/1 x 10/10 = 12.5/10.

Step 3: Simplify the fraction.

We can simplify the fraction by dividing both the numerator and denominator by their greatest common factor (GCF). In this case, the GCF of 12.5 and 10 is 2, so we can divide both by 2. This gives us 12.5/10 = 6.25/5.

Step 4: Check if the fraction can be further simplified.

We can see that the fraction 6.25/5 cannot be simplified any further because 6.25 and 5 do not have any common factors besides 1.

Therefore, the decimal 1.25 can be expressed as a fraction in simplest form as 6.25/5.

How to convert 1.25 into fraction?

To convert 1.25 to a fraction, we need to express it as a ratio of two integers. This can be done by recognizing that the decimal 1.25 can be written as the sum of the whole number 1 and the decimal fraction 0.25.

We can then express 0.25 as a fraction by placing it over 1, which gives us 0.25/1. To simplify this fraction, we need to find a common factor of both the numerator and the denominator that can divide evenly into both. In this case, we can divide both 0.25 and 1 by 0.25, which gives us:

0.25 ÷ 0.25 = 1

1 ÷ 0.25 = 4

So, 0.25/1 simplifies to 1/4.

Now, we can combine the whole number 1 and the fractional part 1/4 to get the mixed number 1 1/4, which is the final answer.

Therefore, 1.25 as a fraction is 5/4 or 1 1/4.

In summary, to convert a decimal to a fraction, we need to identify the whole number part and the fractional part of the decimal, express the fractional part as a fraction, simplify the fraction, and then combine it with the whole number part to get the final answer in the form of a mixed number or an improper fraction.

How to change 1.25 into a fraction?

To convert 1.25 into a fraction, we need to follow a few simple steps.

Step 1: Write the number 1.25 as a fraction with the decimal number as the numerator and 1 as the denominator. This can be done by placing the number over 1, like this:

1.25/1

Step 2: Next, we need to get rid of the decimal point in the numerator. To do this, we can multiply both the numerator and the denominator by a power of 10 that will move the decimal point in the numerator to the right until it becomes a whole number.

In this case, we can multiply both the numerator and the denominator by 100, which will move the decimal point in the numerator two places to the right:

1.25/1 x 100/100 = 125/100

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

In this case, the GCF of 125 and 100 is 25. So, we can divide both the numerator and the denominator by 25:

125/25 = 5

100/25 = 4

Therefore, the fraction equivalent of 1.25 is 5/4.

To check our work, we can convert the fraction 5/4 back to a decimal by dividing the numerator by the denominator:

5 ÷ 4 = 1.25

So, we have successfully converted 1.25 into a fraction and verified our answer.

Is 1.25 and 1 1/4 the same?

Yes, 1.25 and 1 1/4 are equivalent expressions of the same value.

1.25 is a decimal representation of a number that lies between 1 and 2. It can also be written as a mixed number, which consists of a whole number and a fraction. In this case, 1.25 is equivalent to the mixed number 1 1/4.

To understand this, we can convert 1.25 into a fraction by multiplying both the numerator and denominator by 100 to remove the decimal point. This gives us 125/100, which can be simplified by dividing both the numerator and denominator by their greatest common factor (GCF) of 25. This gives us the simplified fraction of 5/4.

Alternatively, we can convert the mixed number 1 1/4 into a fraction by multiplying the whole number (1) by the denominator of the fraction (4) and adding the numerator (1) to get the numerator of the resulting fraction (5). This gives us the fraction 5/4, which is the same as the fraction we obtained from converting the decimal 1.25.

Therefore, we can conclude that 1.25 and 1 1/4 are the same value expressed in different forms. They are equivalent expressions and can be used interchangeably depending on the context. In certain situations, one form may be more appropriate or convenient to use than the other. For example, in some cases, it may be easier to work with fractions rather than decimals, while in others, decimals may be more suitable for calculations or comparisons.

What is equal to 1/4?

One-fourth, often written as 1/4, is a fraction that represents one part out of four equal parts. It is a common fraction and is equivalent to many other fractions and decimal numbers.

One way to think about one-fourth is in terms of shapes. If you divide a square into four equal parts, one of those parts would represent one-fourth of the square. Similarly, if you divide a pizza into four slices, one slice would represent one-fourth of the pizza.

Another way to understand one-fourth is in relation to other fractions. For example, one-fourth is equivalent to two-eighths, three-twelfths, and 0.25 in decimal form. These equivalent forms can be helpful when adding or subtracting fractions with different denominators. For instance, if you want to add 1/4 and 1/8, you can convert 1/4 to 2/8 and then add 2/8 and 1/8 to get 3/8.

One-fourth is also commonly used in measurements. For example, if you measure one cup of flour and only need one-fourth cup for a recipe, you would need to use a measuring cup with quarter marks or a measuring spoon equivalent to one-fourth of a cup. Similarly, in time measurements, one-fourth of an hour is equivalent to 15 minutes.

In geometry, one-fourth can also represent angles. A right angle is equal to one-fourth of a full rotation or 90 degrees. Therefore, if you divide a full rotation into four equal parts, each part represents one-fourth of a rotation or 90 degrees.
