90%

Explanation:

To get a percentage out of a number, simply multiply that number by 100% - use the percentage sign at the end.

0.9xx100%=90%

Alternatively, if you are dealing with fractions, you can put everything over a common denominator factor of 100, and then convert to a fraction of 100.

E.g.:

4/5xx20/20=80/100=80%

17/30xx10/10=170/300=56.67/100~=56.67%

90%

Explanation:

Fractions, decimals and percentages are all different ways of writing the same number.

1/2 = 0.5 = 5/10 = 50/100 = 50%

The decimal 0.9 means 9/10

Change the denominator to 100

9/10 xx10/10 = 90/100 = 90%
