3 x 4 x 5 / 10 x 2 x 6
= 3 x 2 x 2 x 5 x 2/ 5 x 2 x 2 x 3 x 2
= 1
\(\frac{3.4.5}{10.2.6}\)
=\(\frac{3.2.2.5}{2.5.2.2.3}\)
=\(\frac{1}{2}\)
Mk nghĩ z thui.Sai thoi nha!K mk nha!
\(\frac{3\cdot4\cdot5}{10\cdot2\cdot6}\)
\(=\frac{3\cdot2\cdot2\cdot5}{5\cdot2\cdot2\cdot3\cdot2}\)
\(=\frac{1}{2}\)
\(\frac{3\times4\times5}{10\times2\times6}=\frac{1\times2\times1}{2\times1\times2}=\frac{2}{4}=\frac{1}{2}\)
\(\frac{3\times5\times4}{10\times2\times6}\)
\(=\frac{15\times4}{20\times6}\)
\(=\frac{60}{120}=\frac{1}{2}\)
