Question

(3+7/11)*1/4-1/22
(5-3/11):13+1/2
это все один пример помогите это дроби

Answer 1

$1)3+ \frac{7}{11} =3 \frac{7}{11} \\ 2)3 \frac{7}{11} * \frac{1}{4} = \frac{40}{11} * \frac{1}{4} = \frac{10}{11} \\ 3) \frac{10}{11} - \frac{1}{22} = \frac{20-1}{22} = \frac{19}{20} \\ 4)5- \frac{3}{11} =4 \frac{8}{11} \\ 5)4 \frac{8}{11} :13= \frac{52}{11} * \frac{1}{13} = \frac{4}{11} \\ 6) \frac{4}{11} + \frac{1}{2} = \frac{8+11}{22} = \frac{19}{22} \\ 7) \frac{19}{22} : \frac{19}{22} =1$
