化简比,再求比值,六分之一比三分之二,0.375:0....

2/3:0.6 =2/3:3/5 =10:9 =10/9 , 你好,本题已解答,如果满意 请点右下角“采纳答案”。

1/6:2/3=1:4=0.25 0.375:0.625=3:5=0.6 8:8/9=9:8=1.125

45:80=9:16=9/16 九分之四:七分之二=4/9:2/7=14:9=14/9 1.2:3.5=12:35=12/35 八分之五:0.375=5/8:3/8=5:3=5/3

0.625:8分之五 =0.625:5/8 =5 : 5 =1:1 比值=1

6.4:8=64:80=4:5,6.4:8=4;5=0.8; 1 6 : 2 3 =1:4, 1 6 : 2 3 =1:4=0.25;0.375:0.625= 3 8 : 5 8 =3:5,0.375:0.625=3:5=0.6;8: 8 9 =72:8=9:1.8: 8 9 =9:1=9.故答案为:4:5,0.8;1:4,0.25;3:5,0.6;9:1,9.

化简比 一比五分之2 =1÷2/5 =5:2 求比值 0.6比2.4 =0.6÷2.4 =0.25

0.625比1.6 =5/8:8/5 =25:64 比值是:64分之25

(1) 5 8 :15=( 5 8 × 8 5 ):(15× 8 5 )=1:24; 5 8 :15= 5 8 ÷15= 1 24 ;(2)0.8: 3 4 =(0.8×20):( 3 4 ×20)=16:15;0.8: 3 4 =0.8÷ 3 4 = 16 15 ;(3)1.5: 3 5 =(1.5× 10 3 ):( 3 5 × 10 3 )=5:2;1.5: 3 5 =1....

0.24:6=1:25=0.04 1又5分之一∶十分之一=12:1=12

5分之4:15分之4=(4/5×15):(4/15×15)=(12÷4):(4÷4)=3:1 比值3:1=3÷1=3 0.48:0.6=(0.48×100):(0.6×100)=(48÷12):(60÷12)=4:5 比值4:5=4÷5=4/5
