( i )

$= > \frac{1}{7} \times x = 1 \\ \\ \\ \\ = > \frac{1}{7} \times 7 \times x = 1 \times 7 \\ \\ \\ \\ = > x = 7$

( ii ) :

$= > \frac{5}{4} \times x = 1 \\ \\ \\ \\ = > \frac{5}{4} \times \frac{4}{5} \times x = 1 \times \frac{4}{5} \\ \\ \\ \\ = > x = \frac{4}{5}$

( iii ) :

$= > 3\frac{1}{2} \times x = 1 \\ \\ \\ \\ = > \frac{7}{2} \times x = 1 \\ \\ \\ \\ = > \frac{7}{2} \times \frac{2}{7} \times x = 1 \times \frac{2}{7} \\ \\ \\ \\ = > x = \frac{2}{7}$

( iv ) :

$\frac{5}{7} \times x = 1 \\ \\ \\ \\ = > \frac{5}{7} \times \frac{7}{5} \times x = 1 \times \frac{7}{5} \\ \\ \\ \\ = > x = \frac{7}{5}$
