Welcome to Mathnasium’s Maths Tricks series. Today we are finding the percentage amount of any number.

To calculate the percentage of a number, we use the following steps:

- Estimate the answer by rounding the number to the nearest multiple of 50 and using mental maths.
- Convert the percent to a decimal.
- Multiply the number by the decimal.
- Check for reasonableness using your estimate.

Follow the example below to find the percentage.

Step 1: Estimate the answer by rounding the number to the nearest multiple of 50.

Rounding the number 363 to the nearest multiple of 50, we get 350.

Since 87% means 87 *for each 100*, we estimate 87% of 350, which is equal to 304.5 minutes.

Step 2: Convert the percent to a decimal.

87% is eighty seven hundredths. To write this as a decimal, the digits in 87 all move 2 places to the right, leaving us with 0.87.

Step 3: Multiply the number by the decimal.

Multiplying the number 363 by the decimal 0.87, we get an answer of 315.81 minutes.

Step 4: Check for reasonableness.

Our estimate was 304.5, so 315.81 is very reasonable.

Answer: 315.81 minutes.
