A percent is a fraction whose denominator (bottom number) is 100. The percent sign, “%”, indicates percentages or percent (parts per hundred). Percentages are used to express how large/small one quantity is, relative to another quantity. The first quantity usually represents a part or a fraction of the second quantity, which should be 100 or some multiple of 100. percent can be written using the percent sign: 25% or with the word ‘percent’ after a number: 25 percent. When percent follows a whole number, we say ‘percent’. All per cents are fractions with a denominator of 100. We can use fractions and decimals to represent per cents. For example, 1% = 1/100 = 0.01 and 75% = 75/100 = 0.75. To calculate a percent of a quantity, divide the quantity by 100 and multiply by the percent. for Example: What is 10% of 150? 10% = 10/100 So we have 10/100 × 150 = 15%.

## What Percent of x is y?

Above we have discussed how we calculate percentages keeping that thing in mind we can answer this question. To understand this let us take an example.

### What Percent of 5 is 3?

Here in this question, we have to find out what percent of 5 is 3. so let us understand this situation –

let the percent be, z

so, 5 * (z/100) = 3

then, z/100 = 3/5

z = 3/5 *100

z = 3 * 20

z = 60

so here we got the answer 60% of 5 is 3.

With this example, we can form a formula to find out each and every question of this format so let us generate the formula. Here 5 is x and 3 is y. By observing this line,

z = 3/5 *100

**we can easily generate the formula for the condition What Percent of x is y? And that will be, z = y/x * 100.** Now let us see more examples –

### What Percent of 100 is 20?

Here we have to find out what percent of 100 is 20. So let us find out the answer to this question.

z = 20

Answer – 20% of 100 is 20.

Using the formula – z = y/x * 100

here, x = 100 and y = 20

z = 20/100 * 100 = 20
