Question

Помогите решить , пожалуйста

Answer 1

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

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

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

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

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

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