n+2/3=1/9
I did the last one for you. Now it's your turn.
I'll be glad to check your answer.
how do you find the common denominator
are you there?
Yes. I'm here. I'll post an answer in a couple of minutes.

To solve the equation n + 2/3 = 1/9, follow these steps:
Step 1: Simplify both sides of the equation.
The left side already appears to be the simplest form, but the right side can be simplified further.
Since 1/9 is a single fraction, there is no need to simplify it any further.
Step 2: Isolate the n variable.
To isolate the n variable, you need to get rid of the 2/3 on the left side of the equation. You can do this by subtracting 2/3 from both sides of the equation.
n + 2/3 - 2/3 = 1/9 - 2/3
Simplifying the left side:
n = 1/9 - 2/3
Step 3: Find a common denominator.
To subtract fractions, you need to have a common denominator. In this case, the denominators are 9 and 3. The smallest common denominator is their least common multiple, which is 9.
Step 4: Convert fractions to have a common denominator.
n = (1/9) - (2/3) can be rewritten as:
n = (1/9) - (6/9)
Step 5: Subtract the fractions.
n = (1 - 6) / 9
Simplifying the numerator:
n = -5/9
So the solution to the equation n + 2/3 = 1/9 is n = -5/9.
