1化简比. 七分之三比五分之三=5:7 1.2比7.5 =12:75=4:25 四分之一比三分之二=3:82.求比值. 24:16=1.5 六分之五比九分之一=6分之5*9=7.5 八分之五比六分之五=6:8=0.75 7.2:1.8=4

0.75:1.2=5:8 400米:15分之4千米=3千米:2千米

(1)1.25:4.5,=(1.25*100):(4.5*100),=125:450,=(125÷25):(450÷25),=5:18;(2)7: 7 8 ,=(7*8):( 7 8 *8 ),=56:7,=(56÷7):(7÷7),=8:1;(3) 7 15 :1 7 5 ,=( 7 15 *15):( 12 5 *15),=7:36;(4) 3 8 : 1 3 ,=( 3 8 *24 ):( 1 3 *24),=9:8.

7.5:4.5=5:30.75:1.5=1:2四分之三=4:3八分之五=5:8八分之七=7:8

6/5比9/5 =6/5 x5/9 =6/9 =2/3 2.7比10/9=2.7 x9/10 =2.7 x0.9=2.43 21比14 =21/14=3/2=1.5 0.25比0.75 =1/4 x4/3=1/3 40/64 =10/16=5/8 化简比 32比16=2:1 0.15比0.3=15:3=5:1 12/7比8/3 =12/7 :8/3 =36:56=4:7 6比7/2=12:7 4比0.72 =400:72=100:18=50:9
