解方程练习题不带答案

Answer 1

X/4=5/48,

48X=4*5,

48X=20,

X=20/48=5/12,

1/4：X=1/8:1/10,

1/4*1/10=1/8*X,

1/40=X/8,

X=8/40=1/5,

5/X=30:3,

5/X=10,

X=5/10=1/2,

3/4:1/8=x：2,

3/4*2=1/8*X,

3/2=X/8,

X=3*8/2=12,

6.5：x=3.25:4,

6.5*4=3.25*X,

26=3.25X,

X=26/3.25=8,

1.5 :3/4=0.36：x,

1.5X=0.36*3/4,

1.5X=0.27,

X=0.18,
