Question

化简比，求比值，填空？

Answer 1

化简比：
0.6：8=6：80=6÷80=6/80=3:40
5/6:3/4=5/6÷3/4=5/6×4/3=10/9=10:9
0.25:1/2=0.25÷0.5=25÷50=0.5=1/2=1:2
5/8:4/5=5/8÷4/5=5/8×5/4=25/32=25:32
0.04:0.25=4:25
求比值：
0.6：8=6：80=6÷80=0.075
5/6:3/4=5/6÷3/4=5/6×4/3=10/9
0.25:1/2=0.25÷0.5=25÷50=0.5
5/8:4/5=5/8÷4/5=5/8×5/4=25/32
0.04:0.25=0.04÷0.25=0.16
可打了我半天，特别是符号，希望我的回答对你有帮助，也希望有所采纳。谢谢!

Answer 2

0.6:8
=6:80
=3*2:40*2
=3:40

5/6:3/4
=5/6*4/3
=10/9
=10:9

0.25:1/2
=1/4:1/2
=1/4*2
=1/2
=1:2

5/8:4/5
=5/8*5/4
=25/32
=25:32

0.04:0.25
=0.04*100:0.25*100
=4:25
