# Fractions to percentages

1. Change `7/10` to a percentage.

Multiply both sides by `x` (what you do to one side you do to the other) to get `x` on its own.

`(100timescancelx)/cancelx=(10timesx)/7`

`100=(10x)/7`

Multiply both sides by `7` to get `x` on its own.

`100times7=(10xtimescancel7)/cancel7`

`700=10x`

Divide both sides by 10 to get x on its own.

`700/10=(cancel10x)/cancel10`

`x=700/10`

`x=70`

**Answer:** `x=70%`
