First, we have this equation:
(3-1/3)-(2-1/2)
(9/3-1/3)-(4/2-1/2)
(8/3)-(3/2)
2 2/3 - 1 1/2
Make it similar fractions ☺
First find their LCD which is 6. Then, find it's numerator by dividing the LCD to denominator then multiply it to numerator.
(6 ÷ 3)2 = 4
(6 ÷ 2)1 = 3
2 4/6 - 1 3/6 = 1 1/6
Therefore, the answer to your question is 1 1/6 ☺
Hope it helped ☺
