1/1 plus what equals 2/6?

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

1/1 + x = 2/6

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

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

1/1 - 1/1 + x leaves x and 2/6 - 1/1 is -2/3 which means we end up with x = -2/3. Therefore, the answer to "1/1 plus what equals 2/6?" is as follows:

-2/3

It is always good to double-check your math to make sure you did it right. When we entered -2/3 for x in this equation 1/1 + x = 2/6, we get the following true equation which means our math is correct.

1/1 + -2/3 = 2/6
