Answer 2

Let the required number be x, then to create a proportion using the form

`(\%)/(100) = (is)/(of)`

Thus, let 15 be
`1 (1)/(2) \%` of x, then

`(1 (1)/(2))/(100) = (15)/(x) \\ \\ ( (3)/(2) )/(100) =(15)/(x) \\ \\ (3)/(2)x=1,500 \\ \\ x= (1,500*2)/(3) =1,000`

Therefore, 15 is
`1 (1)/(2) \%` of 1,000
