What plus 2/3 equals 3/9?

Here we will show you how to calculate "what" in this sentence: "What plus 2/3 equals 3/9?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x + 2/3 = 3/9

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 2/3 on both sides like this:

x + 2/3 - 2/3 = 3/9 - 2/3

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

-1/3

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

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