\(\dfrac{72\cdot202\cdot28}{303\cdot63\cdot16}=\dfrac{2^3\cdot9\cdot101\cdot2\cdot7\cdot4}{101\cdot3\cdot7\cdot9\cdot2^3\cdot2}\)

\(=\dfrac{4}{3}\)

\(\dfrac{72\times202\times28}{303\times63\times16}=\dfrac{8\times9\times2\times101\times4\times7}{7\times9\times3\times101\times16}=\dfrac{\left(8\times2\times4\right)\times\left(9\times101\times7\right)}{\left(16\times3\right)\times\left(9\times101\times7\right)}=\dfrac{4}{3}\)

\(\frac{72\cdot202\cdot28}{303\cdot63\cdot16}=\frac{8\cdot9\cdot101\cdot2\cdot4\cdot7}{101\cdot3\cdot7\cdot9\cdot8\cdot2}=\frac{4}{3}\)

4/3nha

\(\frac{72}{303}\cdot\frac{202}{63}\cdot\frac{28}{16}\)

\(=\frac{16}{21}\cdot\frac{28}{16}\)

\(=\frac{4}{3}\)
