Упростите отношение: 18/24 72:40 72:112 Заранее Спасибо:3

Решите задачу:

$\frac{18}{24} = \frac{9*2}{12*2} = \frac{9}{12} = \frac{3*3}{4*3} = \frac{3}{4}\\ \\\frac{72}{40}= \frac{36*2}{20*2} = \frac{36}{20} = \frac{18*2}{10*2}= \frac{18}{10}= \frac{9*2}{5*2} = \frac{9}{5} \\\\ \frac{72}{112} = \frac{36*2}{56*2} = \frac{36}{56} = \frac{18*2}{28*2} = \frac{18}{28} = \frac{9*2}{14*2} = \frac{9}{14}$
