Вычислите: 2 1/2 · 48 − 3 2/3; 1/18 + 5 5/12 : 7/36.

1) \(2\frac{1}{2}\cdot48-3\frac{2}{3}=\frac{5}{2}\cdot48-\frac{11}{3}=120-\frac{11}{3}=116\frac{1}{3}\).

2) \(\frac{1}{18}+5\frac{5}{12}:\frac{7}{36}=\frac{1}{18}+\frac{65}{12}\cdot\frac{36}{7}=\frac{1}{18}+\frac{195}{7}=\frac{3509}{126}=27\frac{107}{126}\).

Ответ: \(116\frac{1}{3};\ 27\frac{107}{126}\).
