6/8 minus what equals 1/7?

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

6/8 - x = 1/7

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 6/8 on both sides like this:

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

6/8 - 6/8 - x leaves -x and 1/7 - 6/8 is -17/28 which means we end up with -x = -17/28. Then, you multiply each side by -1 to get x = 17/28. Therefore, the answer to "6/8 minus what equals 1/7?" is as follows:

17/28

It is always good to double-check your math to make sure you did it right. When we entered 17/28 for x in this equation 6/8 - x = 1/7, we get the following true equation which means our math is correct.

6/8 - 17/28 = 1/7
