1/4 minus what equals 3/5?

Here we will show you how to calculate "what" in this sentence: "1/4 minus what equals 3/5?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

1/4 - x = 3/5

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 1/4 on both sides like this:

1/4 - 1/4 - x = 3/5 - 1/4

1/4 - 1/4 - x leaves -x and 3/5 - 1/4 is 7/20 which means we end up with -x = 7/20. Then, you multiply each side by -1 to get x = -7/20. Therefore, the answer to "1/4 minus what equals 3/5?" is as follows:

-7/20

It is always good to double-check your math to make sure you did it right. When we entered -7/20 for x in this equation 1/4 - x = 3/5, we get the following true equation which means our math is correct.

1/4 - -7/20 = 3/5
