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 90 percent of 300. What are the steps?

Step 1: First determine the value of the whole amount. We assume that the whole amount is 300.

Step 2: Determine the percentage, which is 90.

Step 3: Convert the percentage 90% to its decimal form by dividing 90 by 100 to get the decimal number 0.9:

90100 = 0.9

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

90.0 → 9.00 → 0.90

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

0.9 x 300 = 270 (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 = 300 × 90100 = 300 × 0.9 = 270 (answer)

Therefore, the answer is 270 is that 90 percent of 300.
