What is 25% of 75?
To find 25% of 75, we can use the following steps:
Step 1: Convert the percentage to a decimal
To convert 25% to a decimal, we divide it by 100. So, 25% is equal to 0.25.
Step 2: Multiply the decimal by the number
Once we have converted the percentage to a decimal, we can multiply it by the number we want to find the percentage of. In this case, we want to find 25% of 75, so we multiply 0.25 by 75:
0.25 x 75 = 18.75
So, 25% of 75 is equal to 18.75.
Another way to find 25% of 75 is to use proportions. We can set up a proportion where the part is 25% and the whole is 75:
part/whole = percent/100
We know that the percent is 25 and the whole is 75, so we can substitute these values into the proportion:
part/75 = 25/100
To solve for the part, we can cross-multiply:
part x 100 = 75 x 25
part x 100 = 1875
Dividing both sides by 100, we get:
part = 18.75
So, we get the same answer of 18.75, which confirms that 25% of 75 is indeed equal to 18.75.
In summary, to find 25% of 75, we can either convert the percentage to a decimal and multiply it by the number, or use proportions to solve for the part. Both methods will give us the same answer of 18.75.
What is 25 of 75?
In general, to find a percentage of a number, we can use the following steps:
Step 1: Convert the percentage to a decimal
To convert a percentage to a decimal, we divide it by 100. For example, to convert 25% to a decimal, we divide it by 100 and get 0.25.
Step 2: Multiply the decimal by the number
Once we have converted the percentage to a decimal, we can multiply it by the number we want to find the percentage of. For example, if we want to find 25% of 75, we multiply 0.25 by 75:
0.25 x 75 = 18.75
So, 25% of 75 is equal to 18.75.
Alternatively, we can use proportions to find the percentage of a number. We can set up a proportion where the part is the percentage we are looking for and the whole is the original number. Then, we can cross-multiply and solve for the part.
For example, to find 25% of 75 using proportions, we can set up the following proportion:
part/75 = 25/100
To solve for the part, we can cross-multiply:
part x 100 = 75 x 25
part x 100 = 1875
Dividing both sides by 100, we get:
part = 18.75
So, we get the same answer of 18.75 using proportions, which confirms that 25% of 75 is indeed equal to 18.75.
In summary, to find a percentage of a number, we can convert the percentage to a decimal and multiply it by the number, or use proportions to set up a relationship between the part and the whole, and then solve for the part.
How do you figure out 25 percent of a number?
To figure out 25 percent of a number, we can use either mental math or a simple mathematical formula. The formula for finding a certain percentage of a number is:
Percentage x Number = Result
Using this formula, we can easily calculate 25% of a number. Here are the steps:
Step 1: Convert the percentage to a decimal
To convert 25% to a decimal, we divide it by 100. So, 25% is equal to 0.25.
Step 2: Multiply the decimal by the number
Once we have converted the percentage to a decimal, we can multiply it by the number we want to find the percentage of. For example, if we want to find 25% of 100, we multiply 0.25 by 100:

What is 25% out of 100?
When we talk about percentages, we are referring to a fraction of a whole. The term “percent” means “per hundred,” so when we say that something is 25%, we mean that it is 25 out of 100, or 25/100.
In the case of 25% out of 100, we are looking at the fraction 25/100, which can be simplified to 1/4. Therefore, 25% out of 100 is equivalent to 1/4 or 0.25 as a decimal.
To better understand the concept of percentages, it is helpful to consider some practical examples. For instance, if a store is having a sale where everything is 25% off, this means that the price of each item is reduced by 25% of its original value. In other words, if an item originally cost $100, it would now cost $75 (i.e., 25% of $100 is $25, so $100 – $25 = $75).
Another example of how percentages can be used is in the context of grades. Let’s say that a student receives a score of 25 out of 100 on a test. To convert this score to a percentage, we would divide 25 by 100 and multiply the result by 100. This gives us a percentage score of 25%.
Percentages can also be used to compare different quantities. For instance, if we know that 25% of a population is male and 75% is female, we can make comparisons between the two groups. Similarly, if we know that a company’s profits increased by 25% last year, we can compare this to the profits from the previous year to see how much of an increase there was.
In conclusion, understanding percentages is an important skill that can be used in a wide variety of contexts, from shopping to academics to business. When we talk about a percentage, we are referring to a fraction of a whole, with 100 representing the total. In the case of 25% out of 100, the fraction is 1/4 or 0.25 as a decimal. By using percentages, we can make comparisons and analyze data in a more meaningful way.
How do you find 25% of 180?
To find 25% of 180, you can use a few different methods. In this answer, I will describe two common ways to calculate percentages: using fractions and using multiplication.
Method 1: Using Fractions
One way to find 25% of 180 is to convert 25% to a fraction and then multiply it by 180. To convert a percentage to a fraction, you simply divide the percentage by 100. So, 25% can be written as 0.25 (25 ÷ 100 = 0.25). To find 25% of 180 using this method, you would multiply 0.25 by 180:
25% of 180 = 0.25 x 180 = 45
Therefore, 25% of 180 is 45.
Method 2: Using Multiplication
Another way to find 25% of 180 is to use the following formula:
percentage * base = part
In this formula, “percentage” is the percentage you want to find (in this case, 25%), “base” is the number you want to find the percentage of (in this case, 180), and “part” is the result you are looking for.
To find 25% of 180 using this method, you would plug in the values:
25% * 180 = part
To calculate this, you can convert 25% to a decimal by dividing it by 100, which gives you 0.25:
0.25 * 180 = part
Multiplying 0.25 by 180 gives you the answer:
25% of 180 = 0.25 * 180 = 45
Therefore, 25% of 180 is 45.
Conclusion
In conclusion, there are different ways to find a percentage of a number. Two common methods are using fractions and using multiplication. To find 25% of 180, you can convert 25% to a fraction and multiply it by 180, or you can use the formula percentage * base = part and plug in the values. Both methods give the same result, which is 45.
