Tính phân số:
$\frac{19}{6}$+$\frac{19}{8}$
= $\frac{76}{24}$+$\frac{57}{24}$
= $\frac{113}{24}$
$\frac{23}{4}$-$\frac{23}{6}$
= $\frac{69}{12}$-$\frac{46}{12}$
= $\frac{23}{12}$
$\frac{32}{8}$×$\frac{55}{11}$
= $\frac{32}{8}$×5
= $\frac{160}{8}$=20
$\frac{45}{8}$:$\frac{13}{4}$
= $\frac{45}{8}$×$\frac{4}{13}$
= $\frac{180}{104}$=$\frac{45}{26}$
$\frac{19}{6}$ +$\frac{19}{8}$ =5$\frac{13}{24}$
$\frac{23}{4}$ -$\frac{23}{6}$ =1$\frac{11}{12}$
$\frac{32}{8}$ x$\frac{55}{11}$ =4 x 5 =20
