Answer 1

a)

$\frac{\frac{4}{5}}{\frac{2}{3}} \\\\\frac{4}{5}*\frac{3}{2} = \frac{12}{10} = 1.2$

b)

$\frac{\frac{4}{5}}{2} \\\\\frac{4}{5}*\frac{1}{2} = \frac{4}{10} = 0.4$

c)

$\frac{\frac{7}{9}}{\frac{14}{3}}\\ \\\frac{7}{9}* \frac{3}{14}\\\\\frac{21}{126} = \frac{21 \div 21}{126 \div 21} = \frac{1}{6}$

d)

$\frac{\frac{10}{3}}{\frac{5}{9}}\\\\\frac{10}{3}*\frac{9}{5} = \frac{90}{15} = 6$
