### DAV Class 3 Maths Chapter 11 Worksheet 4 Notes

**Adding Like Fractions**

E.g. Add \(\frac{1}{3}\), \(\frac{4}{3}\) and \(\frac{6}{3}\)

{The fractions having same denominator are called like fractions.}

Solution:

\(\frac{1}{3}\) + \(\frac{4}{3}\) + \(\frac{6}{3}\) = \(\frac{11}{3}\)

Add the three numerators.

Keep the denominator as it is.
