Пж помогите 4,5 и 6 задание

Answer 1

4) $15 \frac{5}{12} + x = 10 \frac{11}{12} + 9 \frac{7}{12} = 20 \frac{6}{12}$

$x = 20 \frac{6}{12} - 15 \frac{5}{12} = 5 \frac{1}{12}$

5) $p = \frac{5}{6} +\frac{17}{5} +\frac{8}{3} = \frac{25 + 102 + 80}{30} = \frac{207}{30} =6.9$

6) $\frac{51}{6} \times \frac{2}{5}- \frac{11}{4} \times \frac{10}{11} + \frac{53}{10} = \frac{51}{15} - \frac{25}{10} + \frac{53}{10} = \frac{186}{30} = 6.2$
