1.求比值
80:16
=80\16
=5\1(同时除以16)
=5
0.4:0.24
=40\24(同时乘100)
=5\3(同时除以8)
三分之一:四分之三
=(1\3):(3\4)
=(1\3)\(3\4)
=(1\3)×(4\3)(除以一个不为0的数,就等于乘他的倒数)
=4\9
五分之四:5
=0.8:5
=8\50(同时乘10)
=4\25(同时除以2)

解决问题
1、 两地相距240km,甲、乙两车同时从两地相对开出,3小时相遇,两车的速度之比是6:4,两车的速度各是多少?
240\(6+4)=24
24×6=144(km)
24x4=96(km)
甲:144\3=48(km)
乙:96\3=32(km)
答:甲车速度为48km/小时,乙车速度为32km/小时.
2、 一个圆形花坛的半径是5米,如果将这个圆的半径增加五分之一,这个圆的周长和面积各增加了多少?
5x(1+(1\5))=6m
C圆=2兀r
=2x3.14x5
=31.4m
C圆=2兀r
=2x3.14x6
=37.68m
37.68-31.4=6.28m
答:这个圆的周长增加了6.28m.
S环=兀x(R方-r方)
=3.14x(6方-5方)
=3.14x(36-25)
=3.14x11
=34.54(m方)
答:这个圆的面积增加了34.54m方.
3、 一本故事书150页,第一次读了全书的10%,第二次读了全书的26%,还剩多少页没读?
