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 3.00 percent of 30. What are the steps?

Step 1: first determine the value of the whole amount. We assume that the whole amount is 30.

Step 2: determine the percentage, which is 3.00.

Step 3: Convert the percentage 3.00% to its decimal form by dividing 3.00 into 100 to get the decimal number 0.03:

3.00100 = 0.03

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

3.0 → 0.30 → 0.03

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

0.03 x 30 = 0.9 (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 = 30 × 3.00100 = 30 × 0.03 = 0.9 (answer)

Therefore, the answer is 0.9 is 3.00 percent of 30.
