Điền số thích hợp vào chỗ trống:
a) \(\frac{{ - 11}}{{13}} < \frac{{...}}{{13}} < \frac{{...}}{{13}} < \frac{{...}}{{13}} < \frac{{ - 7}}{{13}}\)
b) \(\frac{{ - 1}}{3} < \frac{{...}}{{36}} < \frac{{...}}{{18}} < \frac{{..1}}{4}\)
Câu a:
\(\frac{{ - 11}}{{13}} < \frac{{ - 10}}{{13}} < \frac{{ - 9}}{{13}} < \frac{{ - 8}}{{13}} < \frac{{ - 7}}{{13}}\)
Câu b:
Ta có: \[\frac{{ - 1}}{3} < \frac{{...}}{{36}} < \frac{{...}}{{18}} < \frac{{ - 1}}{4}\]
Hay \(\frac{{ - 1}}{3} = \frac{{ - 12}}{{36}} < \frac{{...}}{{36}} < \frac{{...}}{{18}} < \frac{{ - 9}}{{36}} = \frac{{ - 1}}{4}\)
Hay \(\frac{{ - 1}}{3} = \frac{{ - 12}}{{36}} < \frac{{ - 11}}{{36}} < \frac{{ - 10}}{{36}} < \frac{{ - 9}}{{36}} = \frac{{ - 1}}{4}\)
Vậy \(\frac{{ - 1}}{3} < \frac{{ - 11}}{{36}} < \frac{{ - 5}}{{18}} < \frac{{ - 1}}{4}\)
