Answer 1

85. 1)

$\frac{21 \times 16}{28} = \frac{3 \times 4}{1} = 12$

2)

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

3)

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

4)

$\frac{45 \times 11}{22 \times 18} = \frac{15 \times 1}{2 \times 6} = \frac{15}{12} = \frac{5}{4} = 1 \frac{1}{4}$

113.
