(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.
