Answer 2

Ответ:

$1. \frac{3}{11} * \frac{7}{12} = \frac{21}{132}=\frac{7}{44} \\\\2. \frac{11}{14} *\frac{7}{8} = \frac{11}{2} *\frac{1}{8} = \frac{11}{16} \\\\3. \frac{7}{8} *\frac{16}{17} = \frac{7}{1} *\frac{2}{17} = \frac{14}{17} \\\\4. \frac{6}{13} * \frac{5}{12} = \frac{1}{13} *\frac{5}{2} = \frac{5}{26}$

Пошаговое объяснение: в 2, 3 и 4:  14 и 7, 16 и 8, 6 и 12 сокращаются.

Answer 3

To calculate these multiplications, you need to multiply the numerators together and the denominators together. Here are the results:

1. (3/11) * (7/12) = (3 * 7) / (11 * 12) = 21/132 = 7/44

2. (11/14) * (7/8) = (11 * 7) / (14 * 8) = 77/112 = 7/16

3. (7/8) * (16/17) = (7 * 16) / (8 * 17) = 112/136 = 14/17

4. (6/13) * (5/12) = (6 * 5) / (13 * 12) = 30/156 = 5/26

Therefore:

1. (3/11) * (7/12) = 7/44
2. (11/14) * (7/8) = 7/16
3. (7/8) * (16/17) = 14/17
4. (6/13) * (5/12) = 5/26
