1/3 minus what equals 2/3?

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

1/3 - x = 2/3

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 1/3 on both sides like this:

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

1/3 - 1/3 - x leaves -x and 2/3 - 1/3 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 "1/3 minus what equals 2/3?" 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 1/3 - x = 2/3, we get the following true equation which means our math is correct.

1/3 - -1/3 = 2/3
