6/9 plus what equals 1/9?

Here we will show you how to calculate "what" in this sentence: "6/9 plus what equals 1/9?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

6/9 + x = 1/9

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 6/9 on both sides like this:

6/9 - 6/9 + x = 1/9 - 6/9

6/9 - 6/9 + x leaves x and 1/9 - 6/9 is -5/9 which means we end up with x = -5/9. Therefore, the answer to "6/9 plus what equals 1/9?" is as follows:

-5/9
