2/1 minus what equals 5/3?

Here we will show you how to calculate "what" in this sentence: "2/1 minus what equals 5/3?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

2/1 - x = 5/3

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 2/1 on both sides like this:

2/1 - 2/1 - x = 5/3 - 2/1

2/1 - 2/1 - x leaves -x and 5/3 - 2/1 is -1/3 which means we end up with -x = -1/3. Then, you multiply each side by -1 to get x = 1/3. Therefore, the answer to "2/1 minus what equals 5/3?" is as follows:

1/3

It is always good to double-check your math to make sure you did it right. When we entered 1/3 for x in this equation 2/1 - x = 5/3, we get the following true equation which means our math is correct.

2/1 - 1/3 = 5/3
