Cách 1
7/11:3/5+4/11:3/5
=35/33+20/33
=55/33
=5/3
Cách 2
7/11:3/5+4/11:3/5
=(7/11+4/11):3/5
=1:3/5
=5/3
C1 : 7/11 : 3/5 + 4/11 : 3/5
= 35/33 + 20/33
= 5/3
C2 : 7/11 : 3/5 + 4/11 : 3/5
= (7/11 + 4/11) : 3/5
= 1 : 3/5
= 5/3
\(=\frac{5}{3}\)

\(\frac{7}{11}\div\frac{3}{5}+\frac{4}{11}\div\frac{3}{5}\)
\(=\left(\frac{7}{11}\div\frac{3}{5}\right)+\left(\frac{4}{11}\div\frac{3}{5}\right)\)
\(=\frac{35}{33}+\frac{20}{33}\)
