Answer:9/723/207/64/517/2013/141/25/212/51/3Step-by-step explanation:1. 2/7 + 3/7 + 4/7 = 9/72. 2/5 + 3/4 (2×4)+(5×3)/(5×4) 8+15/20 = 23/203. 1/2 + 2/3 (1×3)+(2×2)/(2×3) 3+4/6 = 7/64. 1/15 + 2/15 + 9/15 12/15 ÷ 3/3 = 4/55. 9/4 - 7/5 (9×5)-(4×7)/(4×5) 45-28/20 = 17/206. 3/7 + 1/2 (3×2)+(7×1)/(7×2) 6+7/14 = 13/147. 9/12 - 2/8 (9×8)-(12×2)/(12×8) 72-24/96 48/96 ÷ 48/48 = 1/28. 7/8 - 2/3 (7×3)-(8×2) /(8×3) 21-16/24 = 5/219. 9/10 - 1/2 (9×2)-(10×1)/(10×2) 18-10/20 8/20 ÷ 4/4 = 2/510. 10/12 - 1/2 (10×2)-(12×1)/(12×2) 20-12/24 8/24 ÷ 8/8 = 1/3
