mẫu : \(\frac{48\times12}{6}=8\times12=96\)
\(\frac{63\times18}{9}=\)
\(\frac{56\times24}{12}=\)
\(\frac{56\times24}{28}=\)
\(\frac{56\times24}{3\times8}=\)
\(\frac{8\times15\times9}{5\times3\times2}\)
ai xong đầu mình tick cho nha
\(\frac{63x18}{9}=63x2=126\)
\(\frac{56x24}{12}=56x2=112\)
\(\frac{56x24}{28}=2x24=48\)
\(\frac{56x24}{3x8}=\frac{56x24}{24}=56\)
\(\frac{8x15x9}{5x3x2}=\frac{2x4x5x3x3x3}{5x3x2}=4x3x3=36\)
=7x18=126
=56x2=112
=7x8=56
=4x9=36
