Question

用简便方法计算下面各题(用脱式）

（5/11+3/8)x88 17x3/8-3/8 10-2/7÷9/14-5/9 5/6x1/8+1/6÷8

Answer 1

1.        5/11X88+3/8x88=40+33=73

2. 3/8X(17-1)=3/8X16=6

3. 10-(2/7X14/9)-5/9=10-(4/9+5/9)=10-1=9

4.     5/6X1/8+1/6X1/8  =1/8X(5/6+1/6)=1/8X1=1/8

应该是这样吧 

Answer 2

（5/11+3/8)x88
= 5/11x88+3/8x88
=40+33
=73

17x3/8-3/8
=(17-1)x3/8
=16x3/8
=6

10-2/7÷9/14-5/9
=10-2/7x14/9-5/9
=10-4/9-5/9
=10-(4/9+5/9)
=10-1
=9

5/6x1/8+1/6÷8
=5/6x1/8+1/6x1/8
=(5/6+1/6)x1/8
=1/8
