Calculate the result of the following fractions: 3/24 * 23/25 = ? 1/24 * 8/5 = ? 13/14 * 2/32 = ? 19/22 * 11/20 = ? 1 1/4 * 9/14 = ?

Решение:

1. \( \frac{3}{24} \cdot \frac{23}{25} = \frac{1}{8} \cdot \frac{23}{25} = \frac{23}{200} \)
2. \( \frac{8}{1} \cdot \frac{2}{24} = \frac{8}{1} \cdot \frac{1}{12} = \frac{8}{12} = \frac{2}{3} \)
3. \( \frac{13}{14} \cdot \frac{2}{32} = \frac{13}{7} \cdot \frac{1}{16} = \frac{13}{112} \)
4. \( \frac{19}{22} \cdot \frac{11}{20} = \frac{19}{2} \cdot \frac{1}{20} = \frac{19}{40} \)
5. \( 1 \frac{1}{4} \cdot \frac{9}{14} = \frac{5}{4} \cdot \frac{9}{14} = \frac{45}{56} \)

Ответ:
1. \( \frac{23}{200} \)
2. \( \frac{2}{3} \)
3. \( \frac{13}{112} \)
4. \( \frac{19}{40} \)
5. \( \frac{45}{56} \)
