1/3 plus what equals 1/9?

Here we will show you how to calculate "what" in this sentence: "1/3 plus what equals 1/9?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

1/3 + x = 1/9

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 1/3 on both sides like this:

1/3 - 1/3 + x = 1/9 - 1/3

1/3 - 1/3 + x leaves x and 1/9 - 1/3 is -2/9 which means we end up with x = -2/9. Therefore, the answer to "1/3 plus what equals 1/9?" is as follows:

-2/9

It is always good to double-check your math to make sure you did it right. When we entered -2/9 for x in this equation 1/3 + x = 1/9, we get the following true equation which means our math is correct.

1/3 + -2/9 = 1/9
