$Фото задания: (21) 27 − 11$\frac{7}{9}$ =; (22) 2$\frac{7}{12}$ − 1$\frac{13}{24}$ =; (23) 8 − 3$\frac{1}{12}$ =$ Фото задания

Accepted Answer

(21) $27-11\frac{7}{9}=15\frac{2}{9}$.

(22) $2\frac{7}{12}-1\frac{13}{24}=2\frac{14}{24}-1\frac{13}{24}=1\frac{1}{24}$.

(23) $8-3\frac{1}{12}=7\frac{12}{12}-3\frac{1}{12}=4\frac{11}{12}$.

Ответ: (21) $15\frac{2}{9}$; (22) $1\frac{1}{24}$; (23) $4\frac{11}{12}$.

(21) 27 − 11\(\frac{7}{9}\) =; (22) 2\(\frac{7}{12}\) − 1\(\frac{13}{24}\) =; (23) 8 − 3\(\frac{1}{12}\) =
