Answer 1

Подробное решение на фото. Сначала все приводим в неправильные дроби. Потом где можно сокращаем. Там где деление дробь переворачивается.

Answer 2

Let's solve each of these step by step:

1. $4 \frac{1}{12} \times 8 \frac{6}{7}$: First, convert the mixed numbers to improper fractions: $4 \frac{1}{12} = \frac{49}{12}$ and $8 \frac{6}{7} = \frac{58}{7}$.

Now, multiply the two fractions: $\frac{49}{12} \times \frac{58}{7} = \frac{2842}{84} = \frac{1421}{42}$.

2. $5 \frac{3}{7} \times \frac{5}{9} \times \frac{14}{19}$: Convert the mixed number to an improper fraction: $5 \frac{3}{7} = \frac{38}{7}$.

Multiply the fractions: $\frac{38}{7} \times \frac{5}{9} \times \frac{14}{19} = \frac{5320}{1197}$.

3. $5 \frac{5}{7} \times \frac{5}{12} \times 5 \frac{1}{4} \times \frac{6}{7} : 1 \frac{1}{2}$: Convert the mixed numbers to improper fractions: $5 \frac{5}{7} = \frac{40}{7}$ and $5 \frac{1}{4} = \frac{21}{4}$ and $1 \frac{1}{2} = \frac{3}{2}$.

Multiply the fractions: $\frac{40}{7} \times \frac{5}{12} \times \frac{21}{4} \times \frac{6}{7} \div \frac{3}{2} = \frac{1050}{14} = 75$.

4. $\frac{3}{7} : \frac{1}{7} : \frac{11}{25} : \frac{1}{22} : \frac{3}{11}$: Divide the fractions: $\frac{3}{7} : \frac{1}{7} : \frac{11}{25} : \frac{1}{22} : \frac{3}{11} = \frac{3}{7} \times \frac{7}{1} \times \frac{25}{11} \times \frac{22}{1} \times \frac{11}{3} = 1$
