$\dfrac{3}{6}$ $+$ $\dfrac{1}{8}$ $=$ $\dfrac{12}{24}$ $+$ $\dfrac{3}{24}$ $=$ $\dfrac{15}{24}$ $=$ $\dfrac{5}{8}$ $====================================$ $\dfrac{5}{3}$ $-$ $\dfrac{6}{4}$ $=$ $\dfrac{20}{12}$ $+$ $\dfrac{18}{12}$ $=$ $\dfrac{38}{12}$ $=$ $\dfrac{19}{6}$ Bình luận
$\frac{3}{6}$ + $\frac{1}{8}$ = $\frac{1}{2}$ + $\frac{1}{8}$ = $\frac{4}{8}$ + $\frac{1}{8}$ = $\frac{4+1}{8}$ = $\frac{5}{8}$ $\frac{5}{3}$ + $\frac{6}{4}$ = $\frac{5}{3}$ + $\frac{3}{2}$ = $\frac{10}{6}$ + $\frac{9}{6}$ = $\frac{10+9}{6}$ = $\frac{19}{6}$ Bình luận
$\dfrac{3}{6}$ $+$ $\dfrac{1}{8}$ $=$ $\dfrac{12}{24}$ $+$ $\dfrac{3}{24}$ $=$ $\dfrac{15}{24}$ $=$ $\dfrac{5}{8}$

$\dfrac{5}{3}$ $-$ $\dfrac{6}{4}$ $=$ $\dfrac{20}{12}$ $+$ $\dfrac{18}{12}$ $=$ $\dfrac{38}{12}$ $=$ $\dfrac{19}{6}$
$\frac{3}{6}$ + $\frac{1}{8}$
= $\frac{1}{2}$ + $\frac{1}{8}$
= $\frac{4}{8}$ + $\frac{1}{8}$
= $\frac{4+1}{8}$
= $\frac{5}{8}$
$\frac{5}{3}$ + $\frac{6}{4}$
= $\frac{5}{3}$ + $\frac{3}{2}$
= $\frac{10}{6}$ + $\frac{9}{6}$
= $\frac{10+9}{6}$
= $\frac{19}{6}$
