\(\frac{35\times20\times4}{7\times8\times15}\)
\(=\frac{5\times7\times5\times4\times4}{7\times2\times4\times3\times5}\)
\(=\frac{5\times4}{2\times3}\)
\(=\frac{10}{3}\)
35 x 20 x 4/7 x 8 x 15
= 5 x 7 x 2 x 10 x 4/7 x 4 x 2 x 5 x 3
= 10/3
Tk mk nha
\(\frac{35\cdot20\cdot4}{7\cdot8\cdot15}\)
\(=\frac{7\cdot5\cdot5\cdot2\cdot2\cdot4}{7\cdot4\cdot2\cdot3\cdot5}\)
\(=\frac{10}{3}\)
\(\frac{35\cdot20\cdot4}{7\cdot8\cdot15}\)
\(=\frac{5.10}{1.15}\)
\(=\frac{1.10}{3}\)
\(=\frac{10}{3}\)
