Question

Помогите решить , пожалуйста

Answer 1

$9+\frac{3}{17} =\frac{153}{17} +\frac{3}{17} =\frac{156}{17} =9\frac{3}{17}$

$\frac{9}{72} +5=\frac{360}{72} +\frac{9}{72}=\frac{369}{72}=5\frac{9}{72}$

$4\frac{5}{18} +2\frac{4}{18} =\frac{40}{18} +\frac{77}{18} =\frac{117}{18} =6\frac{1}{2}$

$6\frac{7}{15} -2\frac{3}{15}=\frac{97}{15}+\frac{33}{15}=\frac{130}{15} =8\frac{10}{15}=8\frac{2}{3}$

$9\frac{11}{16} +4\frac{5}{16}-2\frac{2}{16}=\frac{155}{16}+\frac{69}{16}-\frac{34}{16}=\frac{190}{16}=11\frac{14}{16} =11\frac{7}{8}$

$15\frac{7}{10} +2\frac{2}{10}-4\frac{1}{10}=\frac{157}{10} +\frac{22}{10}-\frac{41}{10}=\frac{138}{10}=13\frac{8}{10}$
