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 2 percent of 20. What are the steps?

Step 1: first determine the value of the whole amount. We assume that the whole amount is 20.

Step 2: determine the percentage, which is 2.

Step 3: Convert the percentage 2% to its decimal form by dividing 2 into 100 to get the decimal number 0.02:

2100 = 0.02

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

2.0 → 0.20 → 0.02

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

0.02 x 20 = 0.4 (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 = 20 × 2100 = 20 × 0.02 = 0.4 (answer)

Therefore, the answer is 0.4 is 2 percent of 20.
