Question

先化简下列各比，再求出下列各比的比值

2：8分之5 7.7：2.8 3分之8：2分之3 2分之15：10 4分之3：0.6
1.75：8 2.5：2分之11

Answer 1

2:(5/8)
=16:5
=3.2

7.7:2.8
=77:28
=11:4
=2.75

(8/3):(3/2)
=16:9
=16/9

(15/2):10
=15:20
=3:4
=0.75

(3/4):0.6
=0.75:0.6
=75:60
=5:4
=1.25

1.75:8
=(7/4):8
=7:32
=7/32

2.5:(11/2)
=5:11=5/11

Answer 2

2:5/8=16/8:5/8=16:5=16/5
7.7:2.8=77:28=11:4=11/4
8/3:3/2=16/6:9/6=16:9=16/9
15/2:10=15:20=3:4=3/4
3/4:0.6=3/4:3/5=15/20:12/20=15:12=5:4=5/4
1.75:8=7/4:8=7/4:32/4=7:32=7/32
2.5:11/2=5/2:11/2=5:11=5/11
