`1/2+1/3+1/4=3/6+2/6+1/4=5/6+1/4=20/24+6/24=26/24=13/12`
\(\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{4}=\dfrac{6}{12}+\dfrac{4}{12}+\dfrac{3}{12}=\dfrac{6+4+3}{12}=\dfrac{13}{12}\)
\(=\dfrac{6}{12}+\dfrac{4}{12}+\dfrac{3}{12}=\dfrac{6+4+3}{12}=\dfrac{13}{12}\)
\(\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{4}=\dfrac{6}{12}+\dfrac{4}{12}+\dfrac{3}{12}=\dfrac{13}{12}\)
