2/1 plus what equals 1/6?

Here we will show you how to calculate "what" in this sentence: "2/1 plus what equals 1/6?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

2/1 + x = 1/6

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

2/1 - 2/1 + x = 1/6 - 2/1

2/1 - 2/1 + x leaves x and 1/6 - 2/1 is -1 5/6 which means we end up with x = -1 5/6. Therefore, the answer to "2/1 plus what equals 1/6?" is as follows:

-1 5/6

It is always good to double-check your math to make sure you did it right. When we entered -1 5/6 for x in this equation 2/1 + x = 1/6, we get the following true equation which means our math is correct.

2/1 + -1 5/6 = 1/6
