How do write numbers as percentages?

Answer 1

Take the original number, times by 100, put a % after it to get the percentage that the original number is in relation to 1.

E.g. 0.5*100= 50 % of 1

Divide by a different number to get the original number is in relation to the different number.

E.g. 0.5/5=0.1, 0.1*100= 10%
