Question

How do you write 3.71 as a percentage?

Answer 1

`3.71` written as a percentage is `371%`

Explanation:

So writing a percent being given a decimal can be really easy by using these steps:

1) Look at your number and see if there is a number to the left of the decimal point. In this case, `3` comes before `.71`. This is important because it will determine whether the percent will be greater than `99.99...%` or not.

2) Take the decimal point and move it two spaces to the right. In this case, move the decimal point from between the `3` and the `7` and move it two spaces to the right, which would end after the `1`. So you can just disregard your decimal point.

3) Add a percent sign. Just tag a `%` sign to the end of `371` --> `371 %`. And there you have it!

To show why this method works: remember that decimals represent fractions with denominators of powers of 10.

`3.71 = 3 71/100 = 371/100 = 371%`

Hope this helps!
