Question

Сократите дроби: 75/100 42/63 56/60 81/420 72/24 75/24 35/42 36/32 42/49 32/60

Answer 1

$\displaystyle\tt \frac{75}{100}=0,75\\\\\frac{42}{63}=\frac{7\cdot 6}{7\cdot 9}=\frac{2}{3}\\\\\frac{56}{60}=\frac{8\cdot 7}{4\cdot 15}=\frac{14}{15}\\\\\frac{81}{420}=\frac{9\cdot 9}{60\cdot 7}=\frac{3\cdot 9}{20\cdot 7}=\frac{27}{140}\\\\\frac{72}{24}=\frac{8\cdot 9}{8\cdot 3}=3\\\\\frac{75}{24}=\frac{25\cdot 3}{8\cdot 3}=\frac{25}{8}=3,125\\\\\frac{35}{42}=\frac{7\cdot 5}{7\cdot 6}=\frac{5}{6}\\\\\frac{36}{32}=\frac{9\cdot 4}{8\cdot 4}=\frac{9}{8}=1,125$

$\displaystyle \tt \frac{42}{49}=\frac{7\cdot 6}{7\cdot7}=\frac{6}{7}\\\\\frac{32}{60}=\frac{8\cdot4}{15\cdot 4}=\frac{8}{15}$
