Answer 1

$a) \: \frac{x}{3} \times \frac{5}{4} = \frac{x \times 5}{3 \times 4} = \frac{5x}{12}$

$b) \: \frac{2x}{3} \times \frac{9}{10} = 2x \times \frac{3}{10} = x \times \frac{3}{5} = \frac{3}{5}x$

( 2x/3 ×9/10 se simplifica 3 cu 9 = 2x.....)

$c) \: 1 \frac{1}{3} \times \frac{ \times }{6} = \frac{4}{3} \times \frac{x}{6} = \frac{2}{3} \times \frac{x}{3} = \frac{2x}{9}$
