Q.3 Shubham painted \(\frac{2}{3} \) of the wall space in his room. His sister Madhavi helped and painted \(\frac{1}{3} \) of the wall space. How much did they paint together?

Fraction of wall painted by Shubham = \(\frac{2}{3} \)
Fraction of wall painted by Madhavi = \(\frac{1}{3} \)
Fraction of wall painted by Shubham and Madhavi
= \(\frac{2}{3} + \frac{1}{3} = \frac{3}{3} = 1 \)
\(\therefore \) Shubham and Madhavi together painted 1 complete wall in a room.
