在垒球赛季中，朱迪有35次安打。其中1次全垒打、1次三垒打和5次二垒打。其余的安打是单打。她单打占安打总数的百分之多少？

(A) 28% 28%

(B) 35% 35%

(D) 75% 75%

(E) 80% 80%

Answer

Correct choice: (E)

正确答案：（E）

Solution

Answer (E): Judy had a total of 35 hits, of which \(35 - (1 + 1 + 5) = 28\) were singles. Thus \(\frac{28}{35} = \frac{4}{5}\) or 80% were singles.

答案（E）：Judy 一共有 35 次安打，其中 \(35-(1+1+5)=28\) 次是一垒安打。因此 \(\frac{28}{35}=\frac{4}{5}\)，即 80% 是一垒安打。
