\(5x\frac{10}{20}+\frac{10}{20}x5+2x\frac{10}{20}\)
\(=\frac{10}{20}x\left(5+5+2\right)\)
\(=\frac{10}{20}x12\)
\(=\frac{12}{20}\)
\(=\frac{3}{5}\)
# Chúc bạn học tốt #
5*10/20+10/20*5+2*10/20
=(5+5)*10/20+2*10/20
=10*10/20+2*10/20
=5+1
=6
5 * 10/20 + 10/20 * 5 + 2 * 10/20=\(\frac{10}{20}\left(5+5+2\right)=\frac{10}{20}\cdot12=6\)

Bài giải:
\(5\times\frac{10}{20}+\frac{10}{20}\times5+2\times\frac{10}{20}\)
\(=\frac{10}{20}\times\left(5+5+2\right)\)
5. \(\frac{10}{20}+\frac{10}{20}.5+2.\frac{10}{20}\)
= \(\frac{10}{20}\). ( 5 + 5 + 2 )
=\(\frac{10}{20}\). 12
= \(\frac{1}{2}\). 12
= \(\frac{24}{12}\)= 2
Ko biết đúng hay sai nữa ==
\(5\times\frac{10}{20}+\frac{10}{20}\times5+2\times\frac{10}{20}\)
\(=\frac{10}{20}\times\left(5+5+2\right)\)
\(=\frac{10}{20}\times12\)
\(=\frac{1}{2}\times12\)
\(=\frac{6}{1}=6\)
