1、学校40%的学生是男孩，如果这里有240个男孩，那么学校有多少学生？
240/40%=600
2、一个男孩看完了160页故事书，他发现还有20%没看，问这本故事书多少页？ 160/（1-20%0）=200
3、800人中，70%的人喜欢游泳，请问有多少人喜欢游泳？
800*70%=560
1.240/40%=600
2.160/（1-20%）=200
3.800*70%=700
1.240/0.4=600 ,学校里40%的同学是男生.如果有240个男生,那么这个学校一共有多少学生?
2.160/0.8=200 ,一个男孩看了160页的故事书,发现还剩下20%.这本书一共有多少页?
3.800*0.7=560 ,800个人中 70%喜欢游泳 有多少人喜欢游泳?
