化简比,再求比值,六分之一比三分之二,0.375:0....

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

16分之3:0.625 =(16分之3×16):(0.625×16) =3:10 比值: 16分之3:0.625 =16分之3÷0.625 =16分之3÷8分之5 =0.3

3/16:0.625 =3/16:5/8 =(3/16x16):(5/8x16) =3:10 比值:3/10

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

0.625:5/8 =0.625:0.625 =1:1 =1 化简比是1:1,比值是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.

3/0.375 =3000/375 =(3*8*125)/(3*125) =8 3/0.375=8:1

(1)15:10=(15÷5):(10÷5)=3:2;15:10=3:2=3÷2=32;(2)16:29=(16×18):(29×18)=3:4;16:29=3:4=3÷4=34;(3)0.375:0.875=38:78=(38×8):(78×8)=3:7;0.375:0.875=3:7=3÷7=37;(4)0.75小时:30分=45分:30分=(45...
