$\frac{33}{55}$ = $\frac{1}{5}$ $\frac{-56}{72}$ = $\frac{-7}{9}$ $\frac{3.7}{4.9}$ = $\frac{7}{12}$ $\frac{9.6+9.4}{18}$ = $\frac{45}{18}$ Xin hay nhất ! Bình luận
$\dfrac{33}{55} = \dfrac{1}{5}$ $\dfrac{-56}{72} = \dfrac{-7}{9}$ $\dfrac{3.7}{4.9} = \dfrac{21}{36} = \dfrac{7}{12}$ $ \dfrac{9.6 + 9.4}{18} = \dfrac{90}{36} = \dfrac{45}{18}$ Bình luận
$\frac{33}{55}$ = $\frac{1}{5}$
$\frac{-56}{72}$ = $\frac{-7}{9}$
$\frac{3.7}{4.9}$ = $\frac{7}{12}$
$\frac{9.6+9.4}{18}$ = $\frac{45}{18}$

$\dfrac{33}{55} = \dfrac{1}{5}$
$\dfrac{-56}{72} = \dfrac{-7}{9}$
$\dfrac{3.7}{4.9} = \dfrac{21}{36} = \dfrac{7}{12}$
$ \dfrac{9.6 + 9.4}{18} = \dfrac{90}{36} = \dfrac{45}{18}$
