六年级的求比值和化简比
(1求比值
3.2∶4 3 :5/7 25% :2
(2)化简比
100 :25 6 :0.06 2/3 :2/9
过程要写出来
答
(1)3.2:4=32/40=4/5. 3:(5/7)=3/(5/7)=21/5. 25%:2=0.25/2=1/8. (2)100:25=4:1. 6:0.06=600/6=100:1 (2/3):(2/9)=3:1
答
1)3.2:4 3:(5/7) 25%:2 =32/40 =21:5 =0.25/2 =4/5. =1/8. 2)100:25 6:0.06 (2/3):(2/9) =4:1. =600/6 =(6/9)):(2/9) =100:1 =3:1
答
1)3.2:4 3:(5/7) 25%:2
=32/40 =21:5 =0.25/2
=4/5.=1/8.
2)100:25 6:0.06 (2/3):(2/9)
=4:1.=600/6 =(6/9)):(2/9)
=100:1 =3:1
