  • 将下列数字化成最简单的整数比

    6:40

    =3:20

    0.75:1.5

    =75:150

    =1:2

    二分之一:三分之八

    =(1/2):(8/3)

    =(1/2)*(3/8)

    =(1*3)/(2*8)

    =3/16

    =3:16

    二十分之三:0.4

    =(3/20):(2/5)

    =(3/20)*(5/2)

    =(3*5)/(20*2)

    =3/8

    =3:8

    1:三分之二

    =1:(2/3)

    =1*(3/2)

    =3/2

    =3:2

    五分之四:三分之二

    =(4/5):(2/3)

    =(4/5)*(3/2)

    =(4*3)/(5*2)

    =6/5

    =6:5

    27:四分之九

    =27:(9/4)

    =27*(4/9)

    =12

    =12:1

    2.4:0.3

    =24:(3/10)

    =24*(10/3)

    =80

    =80:1.
