Question 1073340
.
<pre>
{{{F/M}}} = {{{13/5}}},      (1)

F - M = 48.   (2)


====> From (1), you have  F = {{{M*(13/5)}}}.   


Substitute it into (2). You will get

{{{M*(13/5)}}} - M = 48.

Multiply it by 5 (both sides) to rid of the denominators. You will get

13M - 5M = 5*48,   or

8M = 5*48  ---->  M = {{{(5*48)/8}}} = 5*6 = 30.


<U>Answer</U>.  30 male and 30 + 48 = 78 female.
