There are a total of 21 apples and avocados at a basket. If the ratio of the number of avocados to the number of apples at the basket is 5 to 2, how many apples are at a basket?
选项
答案
6
解析
比例表达为“the ratio of(the number of avocados)to(the number of apples)at the basket is 5 to 2”。则设the number of avocados(牛油果的个数)为A,设the number of apples(苹果的个数)为B。那么该句表示A: B=5:2,即2A=5B。又因为avocado和apple的总数是21,则A+B=21。解这个二元一次方程组,得到:A=15,B=6。则apple的个数是6。
