Answer 1

3/4-1/2+7/8=9/8
1) 3/4-1/2=3/4-2/4=1/4
2) 1/4+7/8=2/8+7/8=9/8

5/6-2/3+1/4=10/24
1)  5/6-2/3=5/6-4/6=1/6
2)  1/6+1/4=4/24+6/24=10/24

1/3-(1/9+1/6)=1/18
1)  1/9+1/6=6/54+9/54=15/54=5/18
2)  1/3-5/18=1/18

Answer 2

1. 1\5*1\6 = 1/5 * 1/6 = 1/30 2. 2+2\5*2\3 = 2 + 2/5 * 2/3 = 2 + 4/15 = 2 4/15 3. 7\9*4+1\2 = 7/9 * 4 + 1/2 = 28/9 + 4/9 = 32/9 4. 3\7*3+1\3 = 3/7 * 3 + 1/3 = 9/7 + 1/3 = 36/21 + 7/21 = 43/21 5. 2+1\2*1+2\5 = 2 + 1/2 * 1 + 2/5 = 2 + 1/2 + 2/5 = 2 1/2 + 2/5 = 2 11/10 = 3 1/10 6. 7+2\3*2+1\4 = 7 + 2/3 * 2 + 1/4 = 7 + 4/3 + 1/4 = 7 + 16/12 + 3/12 = 7 19/12 = 8 7/12 7. 5+2\5*1+1\9 = 5 + 2/5 * 1 + 1/9 = 5 + 2/5 + 1/9 = 5 9/45 + 5/45 = 5 14
