Devansh painted the 2/3 part of a wall of his room. His sister Janhvi helped him and painted 1/3 part of the same wall. Find out how much part of the room they painted altogether?

Answer»

Devansh painted the wall = (2/3) part 

Janhvi painted the wall = (1/3) part 

∴ They both painted altogether = ((2/3) + (1/3)) part 

= ((2 + 1)/3) part = (3/3) part = 1 part
