\(M=\frac{1}{2}:\left(\frac{1}{3}:\frac{1}{4}:\frac{1}{5}\times\frac{1}{120}\right)=2008\)
\(M=\frac{1}{2}:\left(\frac{1}{3}\times\frac{4}{1}\times\frac{5}{1}\times\frac{1}{120}\right)=2008\)
\(M=\frac{1}{2}:\left(\frac{4}{3}\times\frac{1}{1}\times\frac{1}{24}\right)=2008\)
\(M=\frac{1}{2}:\left(\frac{4}{3}\times\frac{1}{24}\right)=2008\)
\(M=\frac{1}{2}:\left(\frac{1}{3}\times\frac{1}{6}\right)=2008\)
\(M=\frac{1}{2}:\frac{1}{18}=2008\)
\(M=\frac{1}{2}\times\frac{18}{1}=2008\)
\(M=\frac{18}{2}=2008\)
\(M=9=2008\)
\(\dfrac{11}{3}-\dfrac{2}{3}\left(2\dfrac{2}{5}x\dfrac{1}{4}+0,2\right)\)
\(\Leftrightarrow3\left(\dfrac{12}{5}\times\dfrac{1}{4}+0,2\right)\)
\(\Leftrightarrow3\left(\dfrac{3}{5}+\dfrac{1}{5}\right)\)
\(\Leftrightarrow3\times\dfrac{4}{5}\)
\(\Leftrightarrow\dfrac{12}{5}\)
\(\dfrac{11}{3}-\dfrac{2}{3}\times\left(2\dfrac{2}{5}+\dfrac{1}{4}+0,2\right)\)
\(=\dfrac{9}{3}\times\left(\dfrac{12}{5}+\dfrac{1}{4}+\dfrac{1}{5}\right)\)
\(=3\times\left(\dfrac{13}{5}+\dfrac{1}{4}\right)\)
\(=3\times\dfrac{57}{20}\)
\(=\dfrac{171}{20}\)
\(=\dfrac{17}{30}+2\cdot\dfrac{4}{15}=\dfrac{17}{30}+\dfrac{8}{15}=\dfrac{17+16}{30}=\dfrac{33}{30}=\dfrac{11}{10}\)
2/5 x 1/4 : 3/8
=1/10 : 3/8
=4/15
2/5*1/4:3/8
=3/20:3/8
=3/20*8/3
=8/20
=2/5
