What plus 1/2 equals 1/5?

Here we will show you how to calculate "what" in this sentence: "What plus 1/2 equals 1/5?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x + 1/2 = 1/5

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 = 1/5 - 1/2

x + 1/2 - 1/2 leaves x and 1/5 - 1/2 is -3/10 which means we end up with x = -3/10. Therefore, the answer to "What plus 1/2 equals 1/5?" is as follows:

-3/10

It is always good to double-check your math to make sure you did it right. When we entered -3/10 for x in this equation x + 1/2 = 1/5, we get the following true equation which means our math is correct.

-3/10 + 1/2 = 1/5
