How do you convert 1/5 into a decimal and percent?

It is ## 0.2##, or ##20%##.

So you have the fraction ##1/5##.

What the divided sign is, is basically just a division sign. So, to get the decimal, you do ##1 divide 5##.

This makes you get ##0.2##. Now, you need a percentage.

A percentage is a number over ##100##.

To get ##5## to ##100##, you multiply it by ##20##, and do the same for ##1##, leaving you with ##20/100##.

So, your percentage is ##20 %##.
