\(=\dfrac{30+9-4}{12}=\dfrac{35}{12}\)

Answer 3

\(\dfrac{5}{2}+\dfrac{3}{4}-\dfrac{1}{3}=\dfrac{30}{12}+\dfrac{9}{12}-\dfrac{4}{12}=\dfrac{35}{12}\)

Answer 4

\(\dfrac{5}{2}+\dfrac{3}{4}-\dfrac{1}{3}=\dfrac{30}{12}+\dfrac{9}{12}-\dfrac{4}{12}=\dfrac{35}{12}\)

Answer 5

\(\dfrac{5}{2}+\dfrac{3}{4}-\dfrac{1}{3}\\ =\dfrac{30}{12}+\dfrac{9}{12}-\dfrac{4}{12}\\ =\dfrac{30+9-4}{12}=\dfrac{35}{12}\)
