Answer 1

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)

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