Question

How to find out percentage ?

Answer 1

1. First find out the part that is being asked for as a fraction. The denominator probably won’t be 100.
2. Convert that fraction to a decimal. Then you can easily convert the decimal to a percentage!

Example 1. A choir has 22 women and 18 men. Find what percentage of the choir’s members are men.

1. Find out what part (fraction) of the choir’s members are men. That is 18/40, or 9/20.
2. Write 9/20 as a percent. Use equivalent fractions: 9/20 = 45/100 = 45%.

Example 2. One pair of jeans costs $25andtheothercosts$28. How many percent is the price of cheaper jeans of the price of the more expensive jeans?

1. Write what part the cheaper price is of the more expensive price. The answer is 25/28.
2. Write 25/28 as a percentage. A calculator gives 25/28 = 0.8928... Rounded to the nearest whole percent, that’s 89%.
