1)

$\frac{8}{9} x =\frac{2}{9}\\ x =\frac{2}{9}\times\frac{9}{8} \\ x =\frac{1}{4}$

2)

$\frac{5}{9}x = 1 \\ x = 1 \times\frac{9}{5}\\ x = 1.8$

3)

$\frac{4}{7} x = 16 \\ x = 16 \times\frac{7}{4}\\ x = 28$

4)

$5x =\frac{4}{5}\\ x =\frac{4}{5}\times\frac{1}{5}\\ x =\frac{4}{25}= 0.16$

5)

$x \div\frac{9}{16}=\frac{32}{45}\\ x =\frac{9}{16}\times\frac{32}{45}\\ x =\frac{2}{5}= 0.4$

6)

$7 \frac{1}{5}\div x =\frac{9}{10}\\ x = 7 \frac{1}{5}\times\frac{10}{9}\\ x =\frac{36}{5} \times\frac{10}{9}\\ x = 8$
