7/4 minus what equals 3/8?

Here we will show you how to calculate "what" in this sentence: "7/4 minus what equals 3/8?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

7/4 - x = 3/8

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 7/4 on both sides like this:

7/4 - 7/4 - x = 3/8 - 7/4

7/4 - 7/4 - x leaves -x and 3/8 - 7/4 is -1 3/8 which means we end up with -x = -1 3/8. Then, you multiply each side by -1 to get x = 1 3/8. Therefore, the answer to "7/4 minus what equals 3/8?" is as follows:

1 3/8

It is always good to double-check your math to make sure you did it right. When we entered 1 3/8 for x in this equation 7/4 - x = 3/8, we get the following true equation which means our math is correct.
