請給我比例的數學練習,愈多愈好,我快要test 和exam!

你應該係f.2 la,學ratio,咁我就跟番我本書同我d past paper 的問題出比你la
我會由淺到深
level 1
simplify the following ratios
1.18:12
2.2/3:3/2
3.3:9:15
4.14:7:28
5.15:25:20

find a:b:c in each of the following

1.a:b=3:4,a:c=1:6
2.a:b=2:3,a:c=5:1
3.b:c=3:4,a:c=1:6
4.a:b=b:c=3:5

應用題(唔好意思我係英中,冇中文問題 -v-)

1.There are 27 black balls and 18 red balls in a bag.Find the ratio of the number of back balls to that of red balls.

2.The weights of Victor and Peter are in the ratio 6:5.If their total weight is 99kg,find their weights.

level 2
simplify the following ratio

1.1/3:1/5

find a:b in each of the following
1.1/a:1/b=2/3:5/7
