$a,\frac{33\cdot21\cdot18}{9\cdot22\cdot14}=\frac{11\cdot3\cdot7\cdot3\cdot9\cdot2}{9\cdot11\cdot2\cdot7\cdot2}=\frac{9}{2}$

$b,\frac{36\cdot7\cdot12}{6\cdot49\cdot4}=\frac{9\cdot4\cdot7\cdot6\cdot2}{6\cdot7\cdot7\cdot4}=\frac{18}{7}$

Câu trả lời:

$a,\frac{33\cdot21\cdot18}{9\cdot22\cdot14}=\frac{11\cdot3\cdot7\cdot3\cdot9\cdot2}{9\cdot11\cdot2\cdot7\cdot2}=\frac{9}{2}$

$b,\frac{36\cdot7\cdot12}{6\cdot49\cdot4}=\frac{9\cdot4\cdot7\cdot6\cdot2}{6\cdot7\cdot7\cdot4}=\frac{18}{7}$
