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 8 percent of 398. What are the steps?

Step 1: first determine the value of the whole amount. We assume that the whole amount is 398.

Step 2: determine the percentage, which is 8.

Step 3: Convert the percentage 8% to its decimal form by dividing 8 into 100 to get the decimal number 0.08:

8100 = 0.08

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

8.0 → 0.80 → 0.08

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

0.08 x 398 = 31.84 (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 = 398 × 8100 = 398 × 0.08 = 31.84 (answer)

Therefore, the answer is 31.84 is 8 percent of 398.
