Dao Trong Luan 19/08/2017 at 17:51\(\dfrac{1}{2}+\dfrac{2}{3}+\dfrac{3}{4}+\dfrac{1}{3}\)
\(=\left(\dfrac{2}{4}+\dfrac{3}{4}\right)+\left(\dfrac{2}{3}+\dfrac{1}{3}\right)\)
\(=\dfrac{5}{4}+1=\dfrac{5}{4}+\dfrac{4}{4}=\dfrac{9}{4}\)
My answer is faster than Help you solve math's answer.

\(=\left(\dfrac{2}{4}+\dfrac{3}{4}\right)+\left(\dfrac{2}{3}+\dfrac{1}{3}\right)\)
\(=\dfrac{5}{4}+1\)
\(=\dfrac{9}{4}\)
