a) ( -3/7) ÷ 4/12 = -3 × 12/7 × 4 = -36/28 = -9/7

b) 41/4 ÷ 22/5 = 41 × 5/4 × 22 = 205/88

c) 15/11 ÷ 4/5 = 15 × 5/ 11 × 4 = 75/44

d) 17/5 ÷ 4/3 = 17 × 3/5 × 4 = 51/20

e) 1/2 ÷ 1/3 = 1 × 3/2 = 3/2

f) (-19/8) × (-12/7) = -19 × - 12/8 × 7 = 228/56 = 57/14

g) (12/5×7/4) × 3/2 = 12 × 7 × 3/5 × 4 × 2 = 252/40 = 63/10

h) (9/8×5/4) ÷ (1/4×11/3) = (9 × 5/8 × 4) ÷ (1 × 11/4 × 3) = 45/32 ÷ 11/12

45 × 12/32 × 11 = 540/352 = 135/88
