6/7 minus what equals 6/8?

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

6/7 - x = 6/8

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 6/7 on both sides like this:

6/7 - 6/7 - x = 6/8 - 6/7

6/7 - 6/7 - x leaves -x and 6/8 - 6/7 is -3/28 which means we end up with -x = -3/28. Then, you multiply each side by -1 to get x = 3/28. Therefore, the answer to "6/7 minus what equals 6/8?" is as follows:

3/28
