1. If (3/4 - 2/3) + (1/2 + 1/3) is calculated and the answer reduced to simplest terms, what is the denominator of the resulting fraction?
Simplifying the problem:
(9-8)/12 + (5/6)
= 1/12 + 10/12
= 11/12
Denominator is 12
---------------------------
2. 1/2 + (2/3 divided 3/4) - (4/5 x 5/6)= ?
(1/2) + (2/3)(5/3) - (4/6) = ?
(1/2) + (10/9) - (2/3) = ?
(9/18) + (20/18) - (12/18) = ?
17/18
---------------------------
3. If the total cost of x apples is b cents, what is a general formula for the cost, in cents, of y apples?
If x apples costs b cents, each apple = b/x cents
Then y apples will cost y(b/x) cents
