Answer 1

9/14*4/27=2/21. 11/39*13/22=1/6//////////

Answer 2

9/14 × 4/27 =2/21
11/39 × 13/22=1/6

Answer 3

Первое уравнение:

$$\frac{9}{14} \cdot \frac{4}{27} = \frac{9 \cdot 4}{14 \cdot 27} = \frac{2 \cdot 2 \cdot 3}{7 \cdot 2 \cdot 3 \cdot 3} = \frac{4}{63}$$

Ответ: $\frac{4}{63}$.

Второе уравнение:

$$\frac{11}{39} \cdot \frac{13}{22} = \frac{11 \cdot 13}{39 \cdot 22} = \frac{11 \cdot 13}{3 \cdot 13 \cdot 2 \cdot 11} = \frac{1}{6}$$

Ответ: $\frac{1}{6}$.
