a,
2$\frac{1}{4}$= $\frac{9}{4}$
3$\frac{28}{32}$= $\frac{124}{32}$ = $\frac{31}{8}$
5$\frac{35}{200}$ = $\frac{1035}{200}$ = $\frac{207}{40}$
7$\frac{15}{75}$ = 7$\frac{1}{5}$ = $\frac{36}{5}$
b,
$\frac{37}{8}$ = 4$\frac{5}{8}$
$\frac{149}{25}$ = 5$\frac{24}{25}$
$\frac{257}{41}$ = 6$\frac{13}{41}$
Cho mk xin hay nhất please
Thank you
