Solution for 'What is 5% of 40?'

In the following example, consider that:

• The percentage figure is represented by X%
• The whole amount is represented by W
• The portion amount or part is represented by P

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 5 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 5.

Step 3: Convert the percentage 5% to its decimal form by dividing 5 by 100 to get the decimal number 0.05:

5100 = 0.05

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

5.0 → 0.50 → 0.05

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

0.05 x 40 = 2 (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 × 5100 = 40 × 0.05 = 2 (answer)

Therefore, the answer is 2 is that 5 percent of 40.
