Answer 1

Ответ:

$8\frac{3}{5}+1\frac{1}{15}=\frac{8*5+3}{5}+\frac{1*15+1}{15}=\frac{43}{5}+\frac{16}{15}=\frac{129}{15}+\frac{16}{15}=\frac{145}{15}=9\frac{10}{15}=3\frac{2}{3}$

$6+1\frac{1}{3}=\frac{1*3+1}{3}=6*\frac{4}{3}=\frac{6}{1}+\frac{4}{3}= \frac{18}{3}+\frac{4}{3}=\frac{22}{3}=7\frac{1}{3}$

$4\frac{1}{6}-1\frac{1}{3}=\frac{4*6+1}{6}-\frac{1*3+1}{3}=\frac{25}{6}-\frac{4}{3}= \frac{26}{6}-\frac{8}{6}=\frac{18}{6}=3$

$10\frac{1}{2}-4\frac{9}{14}=\frac{10*2+1}{2}-\frac{4*14+9}{14} =\frac{21}{2} -\frac{65}{14} =\frac{147}{14}-\frac{65}{14} =\frac{82}{14}=5\frac{12}{14}=5\frac{6}{7}$

$5\frac{7}{9}-1\frac{1}{6}=\frac{5*9+7}{9}-\frac{1*6+1}{6} =\frac{52}{9} -\frac{7}{6} =\frac{312}{54} -\frac{63}{54} =\frac{249}{54} =4\frac{33}{54}$
