Icleaned 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?

1/9

Step-by-step explanation:

We can make an equation that looks like this:

2/9+6/9+x/9=9/9

Let's cancel out the denominator:

2+6+x=9

Then combine like terms:

8+x=9

Then solve for x:

x=1

Then add in the denominator we canceled out:

x=1/9

Hope I helped, soz if I'm wrong!
