Answer 1

顺序要自己核对清楚哦 

Answer 2

2x X7/10=14
解: 14x=140
x=10

2x-3/5x=4
解: 7x/5=4
7x=20
x=20/7

1/6x÷12=8/9
解: x/6=32/3
x=54

------------------------脱式计算--------------------
7/8X25X4
=7/8*100
=700/8

5-0.64X7/8÷4
=5-0.32*7
=2.76

（0.8+1/2）X5/4
=1+5/8
=13/8
（22+11/12）÷11/24
=22*24/11+2
=50
15/64÷（3/4+1/8）
=15/16*8/7
=15/14
（4/7X5/4+2/7）÷0.2
=5/7*5+10/7
=35/7
