Sum:

\dfrac{3}{11} + \dfrac{13}{5}

  • Set up

\dfrac{15}{55} + \dfrac{143}{55}

  • Find common denominator (55)

\dfrac{15 + 143}{55} = \boxed{\dfrac{158}{55}}

  • Add numerators over common denominator

Difference:

\dfrac{3}{11} - \dfrac{13}{5}

  • Set up

\dfrac{15}{55} - \dfrac{143}{55}

  • Find common denominator (55)

\dfrac{15 - 143}{55} = \boxed{-\dfrac{128}{55}}

  • Subtract numerators over common denominator
