B. \[\frac{9}{{22}} < \frac{{13}}{{22}} < \frac{{18}}{{22}}\]
C. \[\frac{7}{{15}} < \frac{8}{{15}} < \frac{4}{{15}}\]
D. \[\frac{5}{{11}} >\frac{7}{{11}} >\frac{4}{{11}}\]
Giải bởi Vietjack
6 < 7 < 8 nên \[\frac{6}{7} < \frac{7}{7} < \frac{8}{7}\]
9 \[\frac{9}{{22}} < \frac{{13}}{{22}} < \frac{{18}}{{22}}\]
4 < 7 < 8 nên \[\frac{4}{{15}} < \frac{7}{{15}} < \frac{8}{{15}}\]
4 < 5 < 7 nên \[\frac{4}{{11}} < \frac{5}{{11}} < \frac{7}{{11}}\]
