Question

Сократить дроби: 21:30, 74:111, 45:108,120:200,36:90,100:128,48:72,72:120

Answer 1

$\frac{21}{30} = \frac{7}{10} \\\\ \frac{74}{111} = \frac{2}{3} \\\\ \frac{45}{108} = \frac{5}{12} \\\\ \frac{120}{200} = \frac{3}{5} \\\\ \frac{36}{90} = \frac{2}{5} \\\\ \frac{100}{128} = \frac{25}{32} \\\\ \frac{48}{72} = \frac{2}{3} \\\\ \frac{72}{120} = \frac{3}{5}$

Answer 2

1) $\frac{21}{30} = \frac{7}{10} = 0.7$
2) $\frac{74}{111} = \frac{2}{3}$
3) $\frac{45}{108} = \frac{5}{12}$
4) $\frac{120}{200} = \frac{3}{5} = 0.6$
5) $\frac{36}{90} = \frac{2}{5} = 0.4$
6) $\frac{100}{128} = \frac{25}{32}$
7) $\frac{48}{72} = \frac{2}{3}$
8) $\frac{72}{120} = \frac{3}{5} = 0.6$
