Answer 1

\(\dfrac{6}{5}+\dfrac{1}{10}=\dfrac{12}{10}+\dfrac{1}{10}=\dfrac{13}{10}\)

\(\dfrac{4}{3}-\dfrac{5}{12}=\dfrac{16}{12}-\dfrac{5}{12}=\dfrac{11}{12}\)

\(\dfrac{8}{5}\times3=\dfrac{8\times3}{5}=\dfrac{24}{5}\)

\(\dfrac{2}{3}\div\dfrac{4}{3}=\dfrac{2}{3}\times\dfrac{3}{4}=\dfrac{6}{12}=\dfrac{1}{2}\)
