Question

15% of what number is 48?

Answer 1

15% of 320 is 48

Change the percentage to a decimal by dividing it over 100:

`(15)/(100) = 0.15`

Divide 48 by 0.15 to get the answer:

`(48)/(0.15) = 320`

Answer 2

the answer would be 320. all you have to do is set up a proportion.
that looks like 15 over 100 and 48 over n ( n is the number we don't know yet )
and cross multiply to get; 15n and 100*48=4800
now you would have to divide both 15 and 4800 by 15
to get; 15n/15=n and 4800/15=320
so you would get n=320
