Question

Colin has a collection of 120 comic books. Seventy-eight of the comic books were damaged in a flood. What percent of the comic books were damaged?

Answer 1

65%

Explanation:

First, let's write a fraction of how many books damaged compared to how many books total: `78/120`. Now there are two ways you can convert it to percentage:

Method 1: Use a calculator
If you type 78 `divide` 120, you'll get 0.65. Now multiply this number by 100 to get your percentage:
0.65*100=65%

Method 2: Use pen and paper
If you don't have a calculator, your aim to solve it will be to turn `78/120` to a fraction with 100 on the bottom. An easy way to do this is:
`78/120=13/20=65/100`
And the number on the top will be your answer, which is 65%
