Answer 2

Ответ:

$4 \frac{1}{5} \times (12 \frac{1}{4} - x) = 33 - 1.5 \\ 4 \frac{1}{5} \times (12 \frac{1}{4} - x) = 31.5 \\ 12 \frac{1}{4} - x = 31 \frac{1}{2} \div 4 \frac{1}{5} = \frac{63}{2} \div \frac{21}{5} \\ 12 \frac{1}{4} - x = \frac{63}{2} \times \frac{5}{21} \\ 12 \frac{1}{4} - x = \frac{15}{2} = 7 \frac{1}{2} \\ x = 12 \frac{1}{4} - 7 \frac{1}{2} = 12 \frac{1}{4} - 7 \frac{2}{4}$

$x = 11 \frac{5}{4} - 7 \frac{2}{4} = 4 \frac{3}{4}$
