a.$\frac{8}{3}$ +$\frac{8}{5}$ =$\frac{40}{15}$ +$\frac{24}{15}$ =$\frac{40+24}{15}$ =$\frac{64}{15}$
b.$\frac{48}{7}$ -$\frac{3}{2}$ =$\frac{96}{14}$ -$\frac{21}{14}$ =$\frac{75}{14}$
c.$\frac{22}{5}$ x$\frac{7}{4}$ =$\frac{22 .7}{5.4}$ =$\frac{154}{20}$ =$\frac{77}{10}$
d.$\frac{16}{5}$ :$\frac{5}{2}$ =$\frac{16}{5}$ x $\frac{2}{5}$ =$\frac{32}{25}$
