Answer 1

$1) \: x \div \frac{1}{6} = \frac{3}{8} \div 0.5$

$6x = \frac{3}{8} \times \frac{10}{5}$

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

$6x = \frac{3}{4} \: | \div 6$

$x = \frac{3}{24}$

$x = \frac{1}{8}$

$2) \: \frac{0.35}{x} = \frac{0.42}{6}$

$x = \frac{0.35 \times 6}{0.42}$

$x = \frac{0.35}{0.07}$

$x = \frac{35}{7}$

$x = 5$

$3) \: 7 \frac{3}{4} \div \frac{1}{3} = x \div 1 \frac{5}{31}$

$\frac{31}{4} \times3 = \frac{31}{36}x \: | \div \frac{31}{36}$

$9 \times 3 = x \\ x = 27$
