How do you solve this problem?
5/61/3+7/8 divided by (1/2)^3

Middle School Math  PsyDAG, Friday, January 22, 2010 at 11:50am
(1/2/)^3 = 1/2 * 1/2 * 1/2 = 1/8
I am assuming that all the previous data is being divided by (1/2)^3.
(5/6  1/3 + 7/8)/(1/2)^3 =
(5/6  1/3 + 7/8)/1/8 =
Dividing by a fraction is the same as multiplying by the inverse of that fraction.
(5/6  1/3 + 7/8) * 8 =
Find common denominator for addition and subtraction, perform those functions and multiply by 8.
If only the last term is being divided:
5/6  1/3 + (7/8)/(1/2)^3 =
5/6  1/3 + (7/8) * 8 =
The 8's cancel each other out.
5/6  1/3 + 7
Find common denominator for addition and subtraction.
I hope this helps.
