  • 1. 3/2 × 8/3 × 15/4 = 360/24 = 15
    2. 3/2 : 8/3 : 15/4 = 3/2 × 3/8 = 9/16 : 15/4 =
    9/16 × 4/15 = 36/240 = 3/20
    3. 1/3 × 4/5 = 4/15 : 16/9 = 4/15 × 9/16 = 36/240 = 3/20
    4. 8/3 : 4/9 × 15/9 = 8/3 × 9/4 = 72/12 = 6
    5. 5/3 : 5/2 - (3/5 × 9/7) = (5/3 : 5/2) - 27/35
    = (5/3 × 2/5) - 27/35 = 10/15 - 27 /35
    70/105 - 81/105 = -11/105
