Question

2/3x=5/12 5/8除x=5/32 4/15x=20 1/2x+8/9=17/18 24-1/7x=3 2/3x-

Answer 1

2/3x=5/12

x=5/12÷2/3

x=5/12×3/2

x=5/8

5/8÷x=5/32

x=5/8÷5/32

x=5/8×32/5

x=4

4/15x=20

x=20÷4/15

x=20×15/4

x=75

1/2x+8/9=17/18

1/2x=17/18-8/9

1/2x=1/18

x=1/9

24-1/7x=3

1/7x=21

x=147

2/3x-3/4=7/20

2/3x=11/10

x=11/10÷2/3

x=33/20

x=1.65

3/4÷（3/4）=3/4+（1/4）=2/3×（3/2）=1
