Answer 1

$1-\frac{1}{2}= \frac{1}{2} \\1-\frac{1}{4}=\frac{3}{4}\\1-\frac{1}{8}=\frac{7}{8}\\\frac{3}{4}- \frac{1}{4}=\frac{2}{4}\\\frac{4}{5}- \frac{1}{5}=\frac{3}{5}\\\frac{7}{8}- \frac{3}{8}= \frac{4}{8}\\\frac{4}{5}- \frac{2}{5} =\frac{2}{5}\\\frac{3}{8}- \frac{1}{8}= \frac{2}{8} \\ \frac{7}{10}- \frac{3}{10}= \frac{4}{10}\\\frac{9}{10}- \frac{1}{10}+ \frac{2}{10}= \frac{10}{10}=1\\\frac{5}{8}- \frac{3}{8}+ \frac{5}{8}= \frac{7}{8} \\\frac{4}{5}- \frac{3}{5}+ \frac{2}{5}=\frac{3}{5}$
