Answer 1

[Võ Ngọc Phương]

a, \(\dfrac{1}{6}+\dfrac{1}{3}=\dfrac{1}{6}+\dfrac{2}{6}=\dfrac{3}{6}=\dfrac{1}{2}\)

b, \(\dfrac{1}{4}+\dfrac{1}{8}=\dfrac{2}{8}+\dfrac{1}{8}=\dfrac{3}{8}\)

c, \(\dfrac{-5}{12}+\dfrac{2}{-3}=\dfrac{-5}{12}+\dfrac{-8}{12}=\dfrac{-13}{12}\)

Answer 2

[𝓗â𝓷𝓷𝓷]

\(a,\dfrac{1}{6}+\dfrac{1}{3}=\dfrac{1}{6}+\dfrac{2}{6}=\dfrac{3}{6}=\dfrac{1}{2}\)

\(b,\dfrac{1}{4}+\dfrac{1}{8}=\dfrac{2}{8}+\dfrac{1}{8}=\dfrac{3}{8}\)

\(c,\dfrac{-5}{12}+\dfrac{2}{-3}=\dfrac{-5}{12}+\dfrac{-2}{3}=\dfrac{-5}{12}+\dfrac{-8}{12}=\dfrac{-13}{12}\)
