Answer 1

( (1 1/2)³ ·4 1/6 ·8 ·(1/9)² ·1 1/5 - 1 2/3) · 12 3\4 -0 ·8 2/5 + 2 5/9 ·7·1\7= -23/7

1) (1 1\2)³= 1 1/2 · 1 1/2· 1 1/2 = 3/2 · 3/2 · 3\2= 27/8
2) 27\8 · 4 1/6= 27/8 · 25/6= 225/16
3) 225/16  · 8= 225\2
4) (1\9)²= 1/9 · 1/9 = 1/81
5) 225/2 · 1/81= 225/162
6) 225/162 · 1 1/5 = 225/162 · 6\5= 5/3
7) 5/3 - 1 2/3= 5/3 - 5/3= 0
8) 0 · 12 3/4 = 0
9) 0 · 8 2/5 = 0
10) 2 5/9 ·7 = 23/7 · 7= 23
11) 23 · 1/7 = 23/7
12) 0 + 23/7= 23/7
13) 0 - 23/7 = -23/7
