+64 Ok so first, what I did was simplify the denominators of the fractions. 3^2-1 is 8, 5^2-1 is 24, and 7^2-1 is 48. (Because 3 squared is 9, 5 squared is 25, and 7 squared is 49.)
So the fractions are 6/8, 6/24, and 6/48. Then I simplified them. To make it easier, I simplified them into eighths.
6/24 = 2/8 (We could've put 1/4, but I'm gonna use eighths for this problem. You can use whatever you want though.)
6/48 = 1/8
After that we add 6/8 + 2/8 + 1/8 to get 9/8.
So the answer is 9/8, or 1 1/8.
