6/7 minus what equals 2/4?

Here we will show you how to calculate "what" in this sentence: "6/7 minus what equals 2/4?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

6/7 - x = 2/4

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 = 2/4 - 6/7

6/7 - 6/7 - x leaves -x and 2/4 - 6/7 is -5/14 which means we end up with -x = -5/14. Then, you multiply each side by -1 to get x = 5/14. Therefore, the answer to "6/7 minus what equals 2/4?" is as follows:

5/14

It is always good to double-check your math to make sure you did it right. When we entered 5/14 for x in this equation 6/7 - x = 2/4, we get the following true equation which means our math is correct.

6/7 - 5/14 = 2/4
