### Solution for 'What is 3% of four over ten?'

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 3 percent of 0.4. What are the steps?

Step 1: first determine the value of the whole amount. We assume that the whole amount is 0.4.

Step 2: determine the percentage, which is 3.

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

3100 = 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 0.4 = 0.012 (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 = 0.4 × 3100 = 0.4 × 0.03 = 0.012 (answer)

Therefore, the answer is 0.012 is 3 percent of 0.4.
