e, x × $\frac{7}{9}$ =$\frac{2}{3}$ + $\frac{5}{4}$
x × $\frac{7}{9}$ =$\frac{23}{12}$
x =$\frac{23}{12}$ : $\frac{7}{9}$
x = $\frac{69}{28}$
----------
g, x - $\frac{7}{9}$ = $\frac{2}{3}$ : $\frac{6}{5}$
x - $\frac{7}{9}$ = $\frac{5}{9}$
x = $\frac{5}{9}$ + $\frac{7}{9}$
x = $\frac{4}{3}$
----------
h, $\frac{1}{4}$ + $\frac{9}{8}$ : x = $\frac{1}{2}$
$\frac{9}{8}$ : x = $\frac{1}{2}$ - $\frac{1}{4}$
$\frac{9}{8}$ : x = $\frac{1}{4}$
x = $\frac{9}{8}$ : $\frac{1}{4}$
x = $\frac{9}{2}$
----------
i, $\frac{5}{7}$ + x : $\frac{9}{4}$ = $\frac{4}{3}$
x : $\frac{9}{4}$ = $\frac{4}{3}$ - $\frac{5}{7}$
x : $\frac{9}{4}$ = $\frac{13}{21}$
x = $\frac{13}{21}$ . $\frac{9}{4}$
x = $\frac{39}{28}$
