\(\frac{5}{11}+\frac{1}{14}+\frac{2}{5}+\frac{6}{11}+\frac{3}{4}+\frac{6}{25}+\frac{9}{25}\)
\(=\frac{5}{11}+\frac{6}{11}+\frac{1}{14}+\frac{3}{4}+\frac{2}{5}+\frac{6}{25}+\frac{9}{25}\)
\(=1+\frac{23}{28}+1\)
\(=\frac{79}{28}\)

=1/14 +1/4+(2/5+6/25+9/25)+(6/11+5/11)
=4/64+16/64+1+1
=20/64+1+1
=5/16+1+1
=2 và 5/16
\(\frac{5}{11}+\frac{1}{14}+\frac{2}{5}+\frac{6}{11}+\frac{3}{4}+\frac{6}{25}+\frac{9}{25}\)
\(=\left(\frac{5}{11}+\frac{6}{11}\right)+\left(\frac{1}{14}+\frac{3}{4}\right)+\left(\frac{6}{25}+\frac{9}{25}\right)+\frac{2}{5}\)
\(=1+\frac{23}{28}+\frac{3}{5}+\frac{2}{5}\)
\(=1+\frac{23}{28}+1\)
\(=2+\frac{23}{28}\)
\(=\frac{79}{28}\)
