tolong di Jawab ya soalnya no 1,2,3

1. 8/10 : 2 6/9 = 8/10 : 22/10 = 8/10 x 10/22 = 80/220
kalau mau disederhanakan = 80/220 : 2/2 = 40/110 : 2/2 = 20/55 : 5/5 = 8/11

2. 8/9 : 18/30 = 8/9 x 30/18 = 240/162
kalau mau disederhanakan = 240/162 : 2/2 = 120/81 = 1 39/81

3. 3/5 : 18/21 = 3/5 x 21/18 = 63/90
kalau mau disederhanakan = 63/90 : 3/3 = 21/3 0
