Question

Сократите: 4*5/3*6 15*3/11*10 14*9/15*7 2*3/9*8 хотя бы напомните, как решается. забыла.. т-т

Answer 1

$\frac{4 *5 }{3 * 6} = \frac{20}{18} = \frac{20/2}{18/2} = \frac{10}{9} = 1 \frac{1}{9}$

$\frac{15 * 3}{11 * 10} = \frac{45}{110} = \frac{45/5}{110/5} = \frac{9}{22}$

$\frac{14 * 9}{15*7} = \frac{126}{105} = \frac{126/21}{105/21} = \frac{6}{5} = 1 \frac{1}{5}$

$\frac{2*3}{9*8} = \frac{6}{72} = \frac{6/6}{72/6} = \frac{1}{12}$
