The ratio of girls to boys in a class is 2:5.There are 8 girls.
How many new girls must join the class so that there will be equal number of boys and girls?给个翻译和答案.

一个班上女生和男生的比例是2:5,已知女生的个数是8,那么这个班上还要加进去几个新来的女生,才能保证男女生人数一样?
因为女：男=2/5
8/男=2/5
所以男=20人
所以,男-女=20-8=12人
答：还需要进入12个女生,才能使得男女生个数相等
还望采纳O(∩_∩)O哈!
