1/6 plus what equals 8/7?

Here we will show you how to calculate "what" in this sentence: "1/6 plus what equals 8/7?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

1/6 + x = 8/7

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 1/6 on both sides like this:

1/6 - 1/6 + x = 8/7 - 1/6

1/6 - 1/6 + x leaves x and 8/7 - 1/6 is 41/42 which means we end up with x = 41/42. Therefore, the answer to "1/6 plus what equals 8/7?" is as follows:
