7/8 minus what equals 3/5?

Here we will show you how to calculate "what" in this sentence: "7/8 minus what equals 3/5?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

7/8 - x = 3/5

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 7/8 on both sides like this:

7/8 - 7/8 - x = 3/5 - 7/8

7/8 - 7/8 - x leaves -x and 3/5 - 7/8 is -11/40 which means we end up with -x = -11/40. Then, you multiply each side by -1 to get x = 11/40. Therefore, the answer to "7/8 minus what equals 3/5?" is as follows:

11/40

It is always good to double-check your math to make sure you did it right. When we entered 11/40 for x in this equation 7/8 - x = 3/5, we get the following true equation which means our math is correct.

7/8 - 11/40 = 3/5
