5/6 plus what equals 1/5?

Here we will show you how to calculate "what" in this sentence: "5/6 plus what equals 1/5?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

5/6 + x = 1/5

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 5/6 on both sides like this:

5/6 - 5/6 + x = 1/5 - 5/6

5/6 - 5/6 + x leaves x and 1/5 - 5/6 is -19/30 which means we end up with x = -19/30. Therefore, the answer to "5/6 plus what equals 1/5?" is as follows:
