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 0.40 percent of 40. What are the steps?

Step 1: First determine the value of the whole amount. We assume that the whole amount is 40.

Step 2: Determine the percentage, which is 0.40.

Step 3: Convert the percentage 0.40% to its decimal form by dividing 0.40 by 100 to get the decimal number 0.004:

0.40100 = 0.004

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

0.4 → 0.04 → 0.00

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

0.004 x 40 = 0.16 (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 = 40 × 0.40100 = 40 × 0.004 = 0.16 (answer)

Therefore, the answer is 0.16 is that 0.40 percent of 40.
