Вычислите: 2$$\frac{1}{3}$$: ($$\frac{5}{8}$$-$$\frac{3}{8}$$)+2$$\cdot$$\frac{7}{3}$$

Вычислим:

1. $$\frac{5}{8}$$-$$\frac{3}{8}$$ = $$\frac{2}{8}$$ = $$\frac{1}{4}$$
2. 2$$\frac{1}{3}$$ : $$\frac{1}{4}$$ = $$\frac{7}{3}$$ : $$\frac{1}{4}$$ = $$\frac{7}{3}$$ × 4 = $$\frac{28}{3}$$
3. 2$$\cdot$$\frac{7}{3}$$ = $$\frac{14}{3}$$
4. $$\frac{28}{3}$$ + $$\frac{14}{3}$$ = $$\frac{42}{3}$$ = 14
