What plus 4/8 equals 2/9?

Here we will show you how to calculate "what" in this sentence: "What plus 4/8 equals 2/9?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x + 4/8 = 2/9

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 4/8 on both sides like this:

x + 4/8 - 4/8 = 2/9 - 4/8

x + 4/8 - 4/8 leaves x and 2/9 - 4/8 is -5/18 which means we end up with x = -5/18. Therefore, the answer to "What plus 4/8 equals 2/9?" is as follows:

-5/18

It is always good to double-check your math to make sure you did it right. When we entered -5/18 for x in this equation x + 4/8 = 2/9, we get the following true equation which means our math is correct.

-5/18 + 4/8 = 2/9
