星期天,芳芳做完了作业,去楼上的莉莉家玩。一进门,芳芳就闻到了一股香味,她使劲儿闻了闻鼻子:“莉莉姐,什么东西这么香啊!”莉莉指着桌子上的水壶说:“我刚调制的蜂蜜茶,想喝吗?”芳芳口水都快流出来了:“这还用说嘛!”莉莉微微一笑:“蜂蜜茶里蜂蜜的含量为10%,我准备再加100毫升水和10毫升蜂蜜,这样蜂蜜所占的百分比和原来一样吗?”芳芳不假思索地说:“10÷100=10%,新调的蜂蜜茶的蜂蜜含量也是10%,所以蜂蜜所占的百分比没有变化!”莉莉又问道:“怎样求蜂蜜茶中蜂蜜所占的百分比啊?”芳芳想了想说:“用蜂蜜除以蜂蜜茶啊!”

Sunday, Fangfang finished homework, went upstairs to play Lily home. As soon as she came in, Fangfang smelt a scent, and she tried to smell her nose: “Lily, what is so fragrant!” Lily pointed at the kettle on the table and said: “I just made honey tea ”Lily smiled: “ Honey tea honey content of 10%, I’m going to add 100 ml of water and 10 ml of honey, so the percentage of honey and the same as the original? ”Fang Fang said without hesitation: “ 10 ÷ 100 = 10%, the new tune of honey honey is also the content of 10%, so the percentage of honey No change! ”Lily asked again: “ How to find the percentage of honey in the honey ah? ”Fang Fang thought to say: “ Honey divided by honey tea! ”
