[tex]\frac{1}{5}[/tex] a = 11

a = 55

Answer.

2.2

Why:

in percents you always put the percent above 100% ( so it'll look like this---- 20/100) and your number that is left out would be 11 so you put it by your percent like this----20         a

                               100        11

so now you do divide and multiply: you divide 20 by 100 and multiply by 11 to get a which is 2.2
