星期天,我跟妈妈来到了菜市场。菜市场里人来人往,挤得水泄不通。我和妈妈好不容易来到卖白菜的摊子上,卖菜的老奶奶问:“要些白菜吗?”妈妈笑着点点头。“一斤半够吗?”“够!”听着她们的对话,我想:一斤半就是0.75千克,单价是多少呢?老奶奶又说:“3.5元一斤,收你5元钱。”咦,怎么会是5元啊?3.5元一斤白菜,也就是7元一千克,应该是0.75×7=5.25(元);即使是1.5斤,每斤3.5元,也还是1.5×3.5=5.25(元)啊,老奶奶怎么只收5元呢?这个大问号在我的脑海里久久挥之不去。由于菜场太挤,我和妈妈决定去超市买西红柿。
Sunday, I came to the market with my mother. People coming and going in the vegetable market, squeezed too crowded. My mother and I finally came to sell cabbage stalls, selling vegetables, grandmother asked: “to some cabbage? ” Mom nodded with a smile. Listen to their conversation, I think: a pound and a half is 0.75 kilograms, the unit price is how much? Granny said: “3.5 yuan a pound, close you 5 yuan. ”咦, how would be 5 yuan ah? 3.5 yuan a pound of cabbage, which is 7 yuan a kilogram, it should be 0.75 × 7 = 5.25 (yuan); Even 1.5 pounds, 3.5 yuan per catty Or 1.5 × 3.5 = 5.25 (yuan) ah, grandmother how to charge only 5 yuan? This big question mark in my mind a long time lingering. As the market is too crowded, my mother and I decided to go to the supermarket to buy tomatoes.
