1 ) 14 1 / 4 + 7 5 / 6 =
2 ) 7 5 / 24 + 2 3 / 16 =

Answer 1

Дано:

$\bf 14 \frac{1}{4} + 7\frac{5}{6} = ? \\ \\ \bf 7\frac{5}{24} + 2\frac{3}{16} = ?$

Решение:

$\bf 1)14 \frac{ {1}^{( \times 3} }{4} +7 \frac{ {5}^{( \times 2} }{6} = (14 + 7) + ( \frac{3 + 10}{12} ) = 21 + \frac{13}{12} = 21 + 1 \frac{1}{12} = 22 \frac{1}{12} \\ \\ \bf 2)7 \frac{ {5}^{( \times 2} }{24} + 2 \frac{ {3}^{( \times 3} }{16} = (7 + 2) + ( \frac{10 + 9}{48} ) = 9 + \frac{19}{48} = 9 \frac{19}{48}$

Ответ: 1) 22 целые 1/12; 2) 9 целых 19/48.
