Question

i cleaned 6/9 of my room, and my friend cleaned 2/9 of my room . how much of my room do we still have to clean?

Answer 1

1/9

Explanation:

We have been given that

The part of room cleaned by me = 6/9

and the part of the room cleaned by friend = 2/9

Hence, total area of the room cleaned is given by

`(6)/(9)+(2)/(9)\\\\=(8)/(9)`

Therefore, we still have to clean below amount

`1-(8)/(9)\\\\=(1)/(9)`
