Here we will show you how to calculate "what" in this sentence: "5/5 minus what equals 3/7?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

5/5 - x = 3/7

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

5/5 - 5/5 - x = 3/7 - 5/5

5/5 - 5/5 - x leaves -x and 3/7 - 5/5 is -4/7 which means we end up with -x = -4/7. Then, you multiply each side by -1 to get x = 4/7. Therefore, the answer to "5/5 minus what equals 3/7?" is as follows:
