Question

Сократите дроби а) 4/24, 5/20, 4/20, 8/16, 10/40, 5/50; б) 2/4, 3/9, 4/16, 9/45, 11/66, 5/35

Answer 1

$\tt\displaystyle \frac{4}{24}=\frac{4:4}{24:4}=\frac{1}{6}\\\\\\\frac{5}{20}=\frac{5:5}{20:5}=\frac{1}{4}\\\\\\\frac{4}{20}=\frac{4:4}{20:4}=\frac{1}{5}\\\\\\\frac{8}{16}=\frac{8:8}{16:8}=\frac{1}{2}\\\\\\\frac{10}{40}=\frac{10:10}{40:10}=\frac{1}{4}\\\\\\\frac{5}{50}=\frac{5:5}{50:5}=\frac{1}{10}$

------------------------------

$\tt\displaystyle \frac{2}{4}=\frac{2:2}{4:2}=\frac{1}{2}\\\\\\\frac{3}{9}=\frac{3:3}{9:3}=\frac{1}{3}\\\\\\\frac{4}{16}=\frac{4:4}{16:4}=\frac{1}{4}\\\\\\\frac{9}{45}=\frac{9:9}{45:9}=\frac{1}{5}\\\\\\\frac{11}{66}=\frac{11:11}{66:11}=\frac{1}{6}\\\\\\\frac{5}{35}=\frac{5:5}{35:5}=\frac{1}{7}$
