Помогите, никак не могу решить

Answer 1

1)

$\frac{21 \times 16}{28} = \frac{3 \times 16}{4} = 3 \times 4 = 12$

2)

$\frac{36}{18 \times 14} = \frac{2}{14} = \frac{1}{7}$

3)

$\frac{12 \times 5}{15 \times 3} = \frac{4 \times 5}{15} = \frac{4}{3} = 1 \times \frac{1}{3}$

4)

$\frac{45 \times 11}{22 \times 18} = \frac{45}{2 \times 18} = \frac{5}{2 \times 2} = \frac{5}{4} = 1 \times \frac{1}{4}$
