【我】A
【分析】根据(1):p=q-1>0 -> q>1;又得出p/q=(q-1)/q,由于相邻两数互质,所以p/q是最简分数。
根据(2):p/q>1/2,又由题:p<q -> p/q<1,则1/2<p/q<1。这里只能得出p/q的范围,但无法判断是否是最简分数,故insufficient。 【PS】A fraction is said to be at its lowest terms when the numerator and the denominatorcannot be divided by the same number to arrive at a lower valued numerator anddenominator. For example:3/4 is at its lowest terms because the numerator 3 andthe denominator 4 cannot be divided by the same number to lower their values.
欢迎大家指正~~先谢谢了~~ |
