Answer 1

$3 frac{5}{6} +9 frac{5}{24} =3 frac{5*4}{6*4} +9 frac{5}{24} =3 frac{20}{24} +9 frac{5}{24} =12 frac{25}{24} =13 frac{1}{24} \ \ \ 1 frac{5}{6} +7 frac{13}{15} =1 frac{5*5}{6*5} +7 frac{13*2}{15*2} =1 frac{25}{30} + 7frac{26}{30} =8 frac{51}{30} = \ \ \ =9 frac{21}{30} =9 frac{21:3}{30:3} =9 frac{7}{10}$


$frac{11}{21} + frac{1}{10} = frac{11*10}{21*10} + frac{1*21}{10*21} =frac{110}{210} + frac{21}{210} = frac{131}{210} \ \ \ 3 frac{14}{19} + frac{7}{19}= 3 frac{14+7}{19}=3 frac{21}{19} =4 frac{2}{19} \ \ \ 8frac{1}{13} +5=13frac{1}{13}$


$10 frac{3}{14} + frac{11}{14} =10 frac{3+11}{14}=10 frac{14}{14}=11 \ \ \ 3 frac{1}{11} +7 frac{1}{11} =10 frac{1+1}{11} =10 frac{2}{11} \ \ \ 10 frac{11}{30} +1 frac{1}{4} =10 frac{11*2}{30*2} +1 frac{1*15}{4*15} =10 frac{22}{60} +1 frac{15}{60} =11 frac{37}{60}$
