4 5/12-1 1/2:(2 1/6+8/15)×1 4/5

Question

4 5/12-1 1/2:(2 1/6+8/15)×1 4/5

Answer 1

4 5/12 - 1 1/2 : (2 1/6 + 8/15) * 1 4/5 = 3 5/12

1) 2 1/6 + 8/15 = 2 5/30 + 16/30 = 2 21/30 = 2 7/10
2) 1 1/2 : 2 7/10 = 3/2 : 27/10 = 3/2 * 10/27 = (1*5)/(1*9) = 5/9
3) 5/9 * 1 4/5 = 5/9 * 9/5 = 45/45 = 1
4) 4 5/12 - 1 = 3 5/12
