\(\dfrac{3}{5}+\dfrac{4}{5}=\dfrac{7}{5}\)
\(\dfrac{1}{2}+\dfrac{3}{5}=\dfrac{11}{10}\)
\(\dfrac{4}{7}-\dfrac{2}{9}=\dfrac{22}{63}\)
\(2-\dfrac{6}{11}=\dfrac{22}{11}-\dfrac{6}{11}=\dfrac{16}{11}\)
\(\dfrac{3}{4}\times\dfrac{2}{3}=\dfrac{1}{2}\)
\(\dfrac{5}{9}\times3=\dfrac{5}{3}\)

3/5 + 4/5 = 9/5
1/2 + 3/5 = 5/10 + 6/10 = 11/10
4/7 - 2/9 = 36/63 - 14/63 = 22/63
2 - 6/11 = 22/11 - 6/11 = 16/11
3/4 x 2/3 = 1/2
5/9 x 3 = 5/3
7/5 : 7/9 = 7/5 x 9/7 = 9/5
6/11 : 3 = 6/11 x 1/3 = 2/11
