Làm như sau :
\(\frac{3}{5}+\frac{7}{6}+\frac{2}{5}+\frac{5}{6}\)
\(=\left(\frac{3}{5}+\frac{2}{5}\right)+\left(\frac{7}{6}+\frac{5}{6}\right)\)
\(=\frac{3+2}{5}+\frac{7+5}{6}\)
\(=\frac{5}{5}+\frac{12}{6}\)
\(=1+2\)
\(=3\)
\(\frac{3}{5}+\frac{7}{6}+\frac{2}{5}+\frac{5}{6}\)
\(=\left(\frac{3}{5}+\frac{2}{5}\right)+\left(\frac{7}{6}+\frac{5}{6}\right)\)
\(=1+2\)
\(=3\)
\(=\left(\frac{3}{5}+\frac{2}{5}\right)+\left(\frac{7}{6}+\frac{5}{6}\right)\)
\(=1+2=3\)
\(\frac{3}{5}+\frac{7}{6}+\frac{2}{5}+\frac{5}{6}\)
\(=\left(\frac{3}{5}+\frac{2}{5}\right)+\left(\frac{7}{6}+\frac{5}{6}\right)\)
\(=\frac{3+2}{5}+\frac{7+5}{6}\)
\(=\frac{5}{5}+\frac{12}{6}\)
\(=1+2=3\)
3/5+7/6+2/5+5/6
=(3/5+2/5)+(7/6+5/6)
=1+2
=3
\(\frac{3}{5}+\frac{7}{6}+\frac{2}{5}+\frac{5}{6}\)
\(=\left(\frac{3}{5}+\frac{2}{5}\right)+\left(\frac{7}{6}+\frac{5}{6}\right)\)
\(=\frac{5}{5}+\frac{12}{6}\)
\(=1+2\)
\(=3\)
= 3
