If 100% of a number is 15, then what is 50% of the number?

7.5

Step-by-step explanation:

One way in which you could do this problem would be to write and solve an equation of ratios:

100%          15

 =

 50%            x

Cross multipying results in 100x = 750, so that x = 7.5.

50% of the number is 7.5.
