Answer 1

$\frac{5}{6} \div 3.75 = \frac{5}{6} \div 3 \frac{3}{4} = \frac{5 \times 4}{6 \times 15} = \frac{2}{9}$

$\frac{7}{20} \div 4.9 = \frac{7}{20} \div 4 \frac{9}{10} = \frac{7 \times 10}{20 \times 49} = \frac{1}{14}$

$\frac{9}{20} \div 0.9 = \frac{9}{20} \div \frac{9}{10} = \frac{9 \times 10}{20 \times9 } = \frac{1}{2}$
