How do you solve this? I posted this question last night and someone answered but it wasn't the right answer. I have tried so many times and still can't get the right answer. the right answer is suppose to be 15/2
5/61/3+ 7/8/(1/2)^3
Thank you for your help!!

When you posted this question last night it was like this:

drwls answered it correctly following the order of operation the way you typed it.
Now you changed the question.
do you mean (7/8) ÷ (1/2)^3 or
7 ÷ (8/(1/2)^3 ??
e.g. 4/5/6
if 4 ÷ (5/6)
then 4(6/5) = 24/5
if (4/5) ÷ 6
then (4/5)(1/6) = 4/30 = 2/15 , not the same
Please clarify.
A "triple decker" fraction like
7/8/(1/2)^3 is ambiguous 
I meant this one:
(7/8) ÷ (1/2)^3 
ok then
5/61/3+ (7/8) ÷ (1/2)^3
= 5/61/3+ (7/8) ÷ (1/8)
= 5/6  2/6 + 7
= 5/6  2/6 + 42/6
= 45/6
= 15/2
