Answer 3

Answer 4

\(\dfrac{4}{5}+\dfrac{1}{3}=\dfrac{12}{15}+\dfrac{5}{15}=\dfrac{17}{15}\)

\(\dfrac{13}{7}-\dfrac{7}{7}=\dfrac{6}{7}\)

\(\dfrac{4}{9}\times\dfrac{2}{5}=\dfrac{8}{45}\)

\(\dfrac{3}{2}:4=\dfrac{3}{8}\)

Answer 5

\(\dfrac{4}{5}+\dfrac{1}{3}=\dfrac{12}{15}+\dfrac{5}{15}=\dfrac{17}{15}\\ \dfrac{13}{7}-\dfrac{7}{7}=\dfrac{6}{7}\\ \dfrac{4}{9}\times\dfrac{2}{5}=\dfrac{8}{45}\\ \dfrac{3}{2}:4=\dfrac{3}{2}\times\dfrac{1}{4}=\dfrac{3}{8}\)
