a)$\frac{3}{8} \div \frac{2}{5}$
b)$\frac{1}{4} \div \frac{3}{2}$
c)$\frac{3}{8} \div \frac{9}{2}$
d)$\frac{5}{6} \div \frac{1}{2}$
​

Answer 1

$a) \frac{3}{8} \div \frac{2}{5} =$

$\frac{3}{8} \times \frac{5}{2} =$

$\frac{15}{16} = 0.9375$

$b) \frac{1}{4} \div \frac{3}{2} =$

$\frac{1}{4} \times \frac{2}{3} =$

$\frac{2( \div 2)}{12( \div 2)} =$

$\frac{1}{6} = 0.16$

$c) \frac{3}{8} \div \frac{9}{2} =$

$\frac{3}{8} \times \frac{2}{9} =$

$\frac{6( \div 2)}{72( \div 2)} =$

$\frac{3( \div 3)}{36( \div 3)} =$

$\frac{1}{12} = 0.08$

$d) \frac{5}{6} \div \frac{1}{2} =$

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

$\frac{10( \div 2)}{6( \div 2)} =$

$\frac{5}{3} = 1.66$
