4/5 + (-9/11) i need help please

Step-by-step explanation:

Hi! Ace here.

Whenever we have a positive being added to a negative, we can just do the positive subtracted my negative.

So let's rewrite this:

When subtracting and adding fractions, we have to make sure there is a common denominator, and if there isn't a common denominator, then we make a common denominator. The LCM, in this case, is 55, so let's convert the fractions.

Since and both equal 1, the fraction is the same value.

Now we subtract normally with our "new" numbers.

I hope this helped, let me know if you have any questions.
