In all the following examples consider that:

Solution Steps

The following question is of the type "How much X percent of W", where W is the whole amount and X is the percentage figure or rate".

Let's say that you need to find 15 percent of 210. What are the steps?

Step 1: first determine the value of the whole amount. We assume that the whole amount is 210.

Step 2: determine the percentage, which is 15.

Step 3: Convert the percentage 15% to its decimal form by dividing 15 into 100 to get the decimal number 0.15:

15100 = 0.15

Notice that dividing into 100 is the same as moving the decimal point two places to the left.

15.0 → 1.50 → 0.15

Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount:

0.15 x 210 = 31.5 (answer).

The steps above are expressed by the formula:

P = W × X%100

This formula says that:

"To find the portion or the part from the whole amount, multiply the whole by the percentage, then divide the result by 100".

The symbol % means the percentage expressed in a fraction or multiple of one hundred.

Replacing these values in the formula, we get:

P = 210 × 15100 = 210 × 0.15 = 31.5 (answer)

Therefore, the answer is 31.5 is 15 percent of 210.

Solution for '15 is what percent of 210?'

The following question is of the type "P is what percent of W,” where W is the whole amount and P is the portion amount".

The following problem is of the type "calculating the percentage from a whole knowing the part".

Solution Steps

As in the previous example, here are the step-by-step solution:

Step 1: first determine the value of the whole amount. We assume that it is 210.

(notice that this corresponds to 100%).

Step 2: Remember that we are looking for the percentage 'percentage'.

To solve this question, use the following formula:

X% = 100 × PW

This formula says that:

"To find the percentage from the whole, knowing the part, divide the part by the whole then multiply the result by 100".

This formula is the same as the previous one shown in a different way in order to have percent (%) at left.

Step 3: replacing the values into the formula, we get:

X% = 100 × 15210

X% = 1500210

X% = 7.14 (answer)

So, the answer is 15 is 7.14 percent of 210

Solution for '210 is 15 percent of what?'

The following problem is of the type "calculating the whole knowing the part and the percentage".

Solution Steps:

Step 1: first determine the value of the part. We assume that the part is 210.

Step 2: identify the percent, which is 15.

Step 3: use the formula below:

W = 100 × PX%

This formula says that:

"To find the whole, divide the part by the percentage then multiply the result by 100".

This formula is the same as the above rearranged to show the whole at left.

Step 4: plug the values into the formula to get:

W = 100 × 21015

W = 100 × 14

W = 1400 (answer)

The answer, in plain words, is: 210 is 15% of 1400.
