Solve for the unknown
8/52=m/39
I'll give you an example problem. Hopefully, this will help you solve your problem.
4/8 =m/2
numerator 1/ denominator 1 = numerator 2/denominator 2
To solve for m, you simply cross multiply. You multiply one numerator by the other denominator and vice versa.
(4)(2)=8(m)
(i.e. (numerator 1)(denominator 2)=(denominator 1)(numerator 2) )
8=8m
m=1
