What plus 1/2 equals 1/8?

Here we will show you how to calculate "what" in this sentence: "What plus 1/2 equals 1/8?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x + 1/2 = 1/8

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 1/2 on both sides like this:

x + 1/2 - 1/2 = 1/8 - 1/2

x + 1/2 - 1/2 leaves x and 1/8 - 1/2 is -3/8 which means we end up with x = -3/8. Therefore, the answer to "What plus 1/2 equals 1/8?" is as follows:

-3/8

It is always good to double-check your math to make sure you did it right. When we entered -3/8 for x in this equation x + 1/2 = 1/8, we get the following true equation which means our math is correct.

-3/8 + 1/2 = 1/8
