Question

\(\dfrac{2}{5}\) + \(\dfrac{5}{6}\) 

\(\dfrac{11}{10}\) - \(\dfrac{2}{5}\) : \(\dfrac{2}{3}\) 

\(\dfrac{2}{3}\) - \(\dfrac{3}{8}\) 

Answer 1

\(=\dfrac{12}{30}+\dfrac{25}{30}=\dfrac{37}{30}\)

\(=\dfrac{11}{10}-\dfrac{3}{5}=\dfrac{11}{10}-\dfrac{6}{10}=\dfrac{5}{10}=\dfrac{1}{2}\)

\(=\dfrac{16}{24}-\dfrac{9}{24}=\dfrac{7}{24}\)

Answer 2

a: =12/30+25/30=37/30

b: =11/10-3/5=11/10-6/10=5/10=1/2

c: =16/24-9/24=7/24
