Помогите! Дам 15 балов номер 1116 там только сделать д) и е) И номер 1117 если сможете...

$3 \frac{1}{8}+2 \frac{1}{7} =3+2+\frac{1}{8}+ \frac{1}{7} =5+ \frac{8+7}{56}=5 \frac{15}{56}$
$5 \frac{1}{6}+1 \frac{2}{6} =5+1+ \frac{1*2+2*1}{6}=6+ \frac{1+2}{6}=6 \frac{3}{6} =6 \frac{1}{2}$
$\frac{3}{5}- \frac{1}{7}= \frac{3*7-1*5}{35}= \frac{21-5}{35}= \frac{16}{35}$
$\frac{5}{3}- \frac{4}{9}= \frac{5*3-4}{9}= \frac{15-4}{9}= \frac{11}{9}=1 \frac{2}{9}$
$\frac{24}{25}- \frac{7}{15}= \frac{24*3-7*5}{75} = \frac{72-35}{75}= \frac{37}{75}\\ \frac{11}{80}- \frac{11}{90}= \frac{11*9-11*8}{720}= \frac{99-88}{720}= \frac{11}{720}$
$5-2 \frac{1}{13}=5- \frac{27}{13}= \frac{5*13-27}{13}= \frac{65-27}{13}= \frac{38}{13}=2 \frac{12}{13}$
$8 \frac{1}{7}-3 \frac{1}{9}= \frac{57}{7}- \frac{28}{9}= \frac{57*9-28*7}{63}= \frac{513-196}{63}= \frac{317}{63}=5 \frac{2}{63}$
