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

The correct answer is 1

Shubham's wall space in a room $\dfrac{2}{3}$

Madhavi's wall space in a room $\dfrac{1}{3}$


The total area painted by both = $\dfrac{2}{3}$ + $\dfrac{1}{3}$ = $\dfrac{(2+1)}{3}$ = $\dfrac{3}{3}$ = $1$


Therefore, Shubham and Madhavi together painted 1 complete wall in a room.
