选项
C.The two quantities are equal.
D.The relationship cannot be determined from the information given.
解析
a% of 1/b =( a/100)(1/b)
= a/(100b)
b% of 1/a =( b/100)(1/a)
= b/(100a)
因此,我们有:
A项:a/(100b)
B项:b/(100a)
将两项同时乘以100b,得到:
A项:a
B项:b^2/a
再将两项同时乘以 a ,得到:
A项:a^2
B项:b^2
已知0 < a < b,因此0 < a^2 < b^2
答案:
B
