  • 1. 4 1/2 x 1/2 - 1/2 = 4 1/2 = 9/2 x 1/2 = 9/4 - 1/2 = 9/4 - 2/4 = 7/4 = 1 3/4
    2. 4/5 x 3/5 + 2/7 = 4/5 x 3/5 = 12/25 + 2/7 = 134/175
    3. 11/9 x ( 3/5 + 2/3 ) = 1 4/15 = 11/9 x 4/15 = 1 74/135
    4. 5/7 : 2/4 = 5/7 x 4/2 = 20/14 = 10/7 - 1/6 = 53/42 = 1 11/42
    5. 2/7 - 1/9 = 11/63 : 2/9 = 11/63 x 9/2 = 99/126 = 11 / 14
