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

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

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