问题 One month Mary used 1/6 of her monthly salary for a car payment and 1/4 more than the car payment for rent. What fraction of her monthly salary did Mary use that month for the car payment and rent combined?

选项 A、5/24
B、3/8
C、5/12
D、1/2
E、7/12

答案B

解析 某月Mary用月薪的1/6来支付车款,房租比车款多1/4。Mary这个月用于支付车款和房租的钱占其月薪的比例为多少?
解:本题的正确答案为(B)。考生在解此题要注意对比较级的正确理解。More than前后两事物才是比较体,more前的分数“1/4”是后者(payment for the car)的1/4,而不是总体(salary)的1/4,因此车款和房租两者占月薪的比例为:1/6 + 1/6 ×(1+ 1/4)= 3/8
