Пошаговое объяснение:

$1)=>\frac{2}{1} -\frac{7}{5}=> \frac{10-7}{5}=> \frac{3}{5}   \\2)=> 10 - \frac{53}{10} => \frac{100 -53}{10}=> \frac{47}{10}\\3)=> (12+6)+(\frac{1}{6} +\frac{1}{7}) => 18+1 = 19\\4)=> 38\frac{1}{13} +((17+3)+(\frac{2}{13}+\frac{10}{13} )) =>  38\frac{1}{13} + 20\frac{12}{13} => (38+20)+(\frac{1}{13}+\frac{12}{13}) => 58+1 = 59\\5)=> 1 - \frac{3}{25} => \frac{1}{1}-\frac{3}{25}=> \frac{25-3}{25}=>\frac{22}{25}\\6)5\frac{1}{7}\\7)=> \frac{259}{17} - \frac{17}{4}=> \frac{1036-289}{68} => \frac{747}{68}$
