六年级下册解方程和解比例练习题
x = 0.24x－1.8=4.2 x = ×

x－21×=4 x÷=12 3.6x÷2＝2.16

x -x = 4 x－6＝38 x =

x÷= x + x = 4 x－ x＝12

x -25% x=10 x＋x = 4x－3 ×9 = 29

x－0.25= 4+0.7x =102 x =×

解比例:
x:10=: 0.4:x=1.2:2 =

:=:x 0.8:4=x:8 :x=3:12

1.25:0.25=x:1.6 = =

x: =6: = 45:x=18:26

2.8:4.2=x:9.6 :x=: 2.8:4.2=x:9.6

x:24= : 8:x=: :=x:
