if you mean
a/4 = b/5 = 2/3,
then do it the same way I just showed you for your previous post
I don't know what to multiply
do i multiply 4, 5 , and 3? and 2?
a statement such as
a/4 = b/5 = 2/3
means that all fractions equal each other and are equal to 2/3
so set each one equal to 2/3

a/4 = 2/3
or a = 8/3
b/5 = 2/3
or b = 10/3

the ab = (8/3)(10/3) = 80/9 or 8 8/9
