4/8 minus what equals 3/2?

Here we will show you how to calculate "what" in this sentence: "4/8 minus what equals 3/2?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

4/8 - x = 3/2

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 4/8 on both sides like this:

4/8 - 4/8 - x = 3/2 - 4/8

4/8 - 4/8 - x leaves -x and 3/2 - 4/8 is 1 which means we end up with -x = 1. Then, you multiply each side by -1 to get x = -1. Therefore, the answer to "4/8 minus what equals 3/2?" is as follows:

-1

It is always good to double-check your math to make sure you did it right. When we entered -1 for x in this equation 4/8 - x = 3/2, we get the following true equation which means our math is correct.
