Question

2 : 1/4 ((1 1/2 +2 2/3): 3 3/4 - 2/3): 8 8/9

Answer 1

2 : 1/4((1 1/2 + 2 2/3) : 3 3/4 - 2/3) : 8 8/9 = 2/5
1) 1 1/2 + 2 2/3 = 1 3/6 + 2 4/6 = 3 7/6 = 4 1/6
2) 4 1/6 : 3 3/4 = 25/6 : 15/4 = 25/6 * 4/15 = 10/9 = 1 1/9
3) 1 1/9 - 2/3 = 1 1/9 - 6/9 = 10/9 - 6/9 = 4/9
4) 2 : 1/4 = 2 * 4 = 8
5) 8 * 4/9 = 32/9 = 3 5/9
6) 3 5/9 : 8 8/9 = 32/9 : 80/9 = 32/9 * 9/80 = 32/80 = 2/5
