To determine the percent of a number do the following steps:
- Multiply the number by the percent (e.g. 87 * 68 = 5916)
- Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)
- Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)
Determining Percentage Example: 68 is what percent of 87?
- Divide the first number by the second (e.g. 68 ÷ 87 = 0.7816)
- Multiply the answer by 100 (Move decimal point two places to the right) (e.g. 0.7816*100 = 78.16)
- Round to the desired precision (e.g. 78.16 rounded to the nearest whole number = 78)
- Follow the answer with the % sign (e.g. 68 is 78% of 87)
