Decimals to percentages 

1. Change `0.25` to a percentage

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

  `(100timescancelx)/cancelx=(1timesx)/0.25` 

 `100=x/0.25`

Multiply both sides by `0.25` to get `x` on its own.

   `0.25times100=(xtimescancel0.25)/cancel0.25`

`x=100times0.25`

`x=25` 

Answer: `x=25%`
