What plus 1/2 equals 2/1?

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

x + 1/2 = 2/1

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 = 2/1 - 1/2

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

1 1/2

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

1 1/2 + 1/2 = 2/1
