Question

Middle School Middies 队赢的场数与输的场数之比为 $11/4$ ，没有平局。四舍五入到最接近的整数百分比，这支队输了百分之多少的比赛？

The ratio of the number of games won to the number of games lost (no ties) by the Middle School Middies is $11/4.$ To the nearest whole percent, what percent of its games did the team lose?

$24\%$

$27\%$

$36\%$

$45\%$

$73\%$

答案：B

知识点：比与比例百分数

难度评级：1120

解答：

可以把这支队看成每 $15$ 场比赛中赢 $11$ 场、输 $4$ 场。

输掉的百分比为 $\dfrac4{15}\cdot100\%\approx 27\%$ 。

所以正确答案是 B。

The team can be viewed as winning $11$ games and losing $4$ games in each batch of $15$ games.

The percent lost is $\dfrac4{15}\cdot100\%\approx 27\%$ .

Thus, B is the correct answer.
