Jawaban:

$frac{4x}{5} div frac{2x}{3} = frac{4x}{5} times frac{3}{2x} \ = frac{2}{5} times 3 \ = frac{6}{5}$

$frac{2}{3x + 1} div frac{1}{x - 1} = frac{2}{3x + 1} times (x - 1) \ = frac{2x - 2}{3x + 1}$

$frac{3m}{5a - 1} div frac{2m}{3a + 1} = frac{3m}{5a - 1} times frac{3a + 1}{2m} \ = frac{3}{5a - 1} times frac{3a + 1}{2} \ = frac{3(3a + 1)}{2(5a - 1)} \ = frac{9a + 3}{10a - 2}$
