13$$\frac{18}{25} - 4 =$$ 18$$\frac{13}{15} - 7=$$ $$5 - 2\frac{1}{3} =$$ $$2 + 3\frac{14}{15} =$$

Решение:

1. $$13\frac{18}{25} - 4 = 9\frac{18}{25}$$
2. $$18\frac{13}{15} - 7 = 11\frac{13}{15}$$
3. $$5 - 2\frac{1}{3} = 4\frac{3}{3} - 2\frac{1}{3} = 2\frac{2}{3}$$
4. $$2 + 3\frac{14}{15} = 5\frac{14}{15}$$

Ответ:

1. $$9\frac{18}{25}$$
2. $$11\frac{13}{15}$$
3. $$2\frac{2}{3}$$
4. $$5\frac{14}{15}$$
