求比值化简比1求比值 8/5 : 2/5 = 15.6 : 1.17 = 4.375 : 1.875 = 2 : 35/？

Answer 1

1求比值
8/5 :2/5
=8/5×5/2
=4
15.6 :1.17
=1560÷117
=(1560÷39)÷(117÷39)
=40÷3
=40/3
4.375 :1.875
=4又3/8 :1又7/8
=35/8 :15/8
=35/8×8/15
=7/3
2 :35/6
=2×6/35
=12/35
1/4 :3/4
=1/4×4/3
=1/3
1.5 :2.4
=1又1/2 :2又2/5
=3/2 :12/5
=3/2×5/12
=5/8
5/8 :1/8
=5/8×8
=5
2/9 :1/7
=2/9×7
=14/9
5/6 :1/3
=5/6×3
=5/2
2化简比
3.5 :8.4
=(3.5×10) :(8.4×10)
=35 :84
=(35÷7) :(84÷7)
=5 :12
1.2 :1.4
=(1.2×5) :(1.4×5)
=6 :7
3/10 :4/25
=(50×3/10) :(50×4/25)
=15 :8
9/2 :12
=(9/2×2/3) :(12×2/3)
=3 :8
9/4 :9/4
=(9/4×4/9) :(9/4×4/9)
=1 :1
24 :18
=(24÷6) :(18÷6)
=4 :3
12厘米：60米
=12厘米：6000厘米
=(12÷12)：(6000÷12)
=1 ：500
1小时：1小时30分
=1小时：1.5小时
=(1×2)：(1.5×2)
=2：3
1.8：27
=(1.8×5)：(27×5)
=9：135
=(9÷9)：(135÷9)
=1：15
3.125：5/4
=3又1/8：5/4
=11/8：5/4
=11/8×4/5
=11/10
=11：10,6,8/5 : 2/5 = 15.6 : 1.17 = 4.375 : 1.875 = 2 : 35/6 = 1/4 : 3/4 = 1.5 : 2.4=
5/8 : 1/8 = 2/9 : 1/7 = 5/6 : 1/3 =
2化简比
3.5 : 8.4 = 1.2 : 1.4 = 3/...,1,自己做,0,求比值化简比
