Question

How do you do number 38 to 40 please help

Answer 1

38. Division by 1/3 is the same as multiplication by 3.

$\frac{5}{6} \times 3 = 5 \times \frac{3}{6} = 5 \times \frac{1}{2} = \frac{5}{2}$

$\frac{1}{2} \times 3 = \frac{3}{2}$

$\frac{1}{9} \times 3 = \frac{3}{9} = \frac{1}{3}$


40. Division by 1/2 is the same as multiplication by 2.

$x \times 2 = \frac{6}{8}$
$x = \frac{6}{8} \times \frac{1}{2} = \frac{3}{8}$

$3 \times 2 = 6$

$x \times 2 = 5$
$x = \frac{5}{2}$
