Answer 1

(8/11+3/22):5/11=9/10
19/24:(3/16+5/24)=2

Answer 2

в 1 не 9/10 а 1 9/10

Answer 3

(8/11+3/22):5/11=$1 frac{9}{10}$

1) $frac{8}{11} + frac{3}{22} = frac{16}{22} + frac{3}{22} = frac{19}{22}$

2) $frac{19}{22} / frac{5}{11} = frac{19*11}{22*5} = frac{19*1}{2*5} = frac{19}{10} =1 frac{9}{10}$


19/24:(3/16+5/24)=2

1)  $frac{3}{16} + frac{5}{24} = frac{9}{48} + frac{10}{48} = frac{19}{48}$

2)$frac{19}{24} / frac{19}{48} = frac{19*48}{24*19} = frac{1*2}{1*1} =2$

Answer 4

вот так надо?
