To solve this problem you must apply the proccedure shown below:
1. You have that the quintuple of 48/25 is:
=(48/25)5
=48x5/25
2- When you simplify, you obtain:
=48/5
3. Then, 3/4 of the quintuple of 48/25 is:
=(48/5)(3/4)
=48x3/5x4
=144/20
=36/5
4. Now, you have:
(9/8)x=36/5
x: the fraction asked
5. When you clear "x", you have:
x=36x8/5x9
x=288/45
x=32/5
The answer is: 32/5
