{7 1/ 2 + 1/2 ÷ 1/2 of 1/4 - 2/5 x 2 1/ 3 ÷ 1 7/ 8 of (1 2/ 5 - 1 1/ 3) } =?

Correct Answer: 41/30

Explanation:

Given expression = 15/2 + 1/2 ÷ 1/8 - 2/5 x 7/3 ÷ 15/8 x (7/5 - 4/3)
= 15/2 + 4 - 2/5 x 7/3 ÷ 15/8 x 1/15
= 15/2 + 4 - 2/5 x 7/3 ÷ 1/8
= 15/2 + 4 - 2/5 x 7/3 x 8/1
= 15/2 + 4 - 112/15
= 23/2 - 112/15
= 121/30
= 41/30
