Answer 1

a) $\displaystyle x*\frac{14}{15}= \frac{7}{9}|:\frac{14}{15}$
$\displaystyle x= \frac{7}{9}*\frac{15}{14}$
$\displaystyle x= \frac{1}{3}*\frac{5}{2}$
$\displaystyle x= \frac{5}{6}$

b) $\displaystyle \frac{16}{19}:x=\frac{8}{11}$
$\displaystyle x= \frac{16}{19}:\frac{8}{11}$
$\displaystyle x= \frac{16}{19}*\frac{11}{8}$
$\displaystyle x= \frac{2}{19}*\frac{11}{1}$
$\displaystyle x= \frac{22}{19}$
$\displaystyle x=1\frac{3}{19}$
