Question

( 2/3+1/2) - 1/3

(7/2 + 1/4 + 1) - 3/8

(2/3 + 1/2) - 1/2

(2 - 1/2) - (3/4-1/2)

Answer 1

(2/3+1/2)-1/3 = (4/6+3/6)-2/6 = 7/6-2/6 = 5/6

(7/2+1/4+1)-3/8 = (28/8+2/8+8/8)-3/8 = (30/8+8/8)-3/8 = 38/8-3/8 = 35/8

(2/3+1/2)-1/2 = (4/6+3/6)-3/6 = 7/6-3/6 = 4/6 = 2/3

(2-1/2)-(3/4-1/2) = (8/4-2/4)-(3/4-2/4) = 6/4-1/4 = 5/4
