\(=\dfrac{5}{6}+\dfrac{1}{4}=\dfrac{13}{12}\)
\(\dfrac{5}{2}x\dfrac{1}{3}+\dfrac{1}{4}=\dfrac{5}{6}+\dfrac{1}{4}=\dfrac{20}{24}+\dfrac{6}{24}=\dfrac{26}{24}=\dfrac{13}{12}\)
\(\dfrac{5}{2}\times\dfrac{1}{3}+\dfrac{1}{4}=\dfrac{5}{6}+\dfrac{1}{4}=\dfrac{10}{12}+\dfrac{3}{12}=\dfrac{13}{12}\)
\(\dfrac{5}{2}\times\dfrac{1}{3}+\dfrac{1}{4}=\dfrac{5}{6}+\dfrac{1}{4}=\dfrac{20}{24}+\dfrac{6}{24}=\dfrac{26}{24}=\dfrac{13}{12}nha\)
