What minus 2/7 equals 1/3?

Here we will show you how to calculate "what" in this sentence: "What minus 2/7 equals 1/3?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x - 2/7 = 1/3

To solve this equation, we want x alone on the left side of the equation so we start by adding 2/7 on both sides like this:

x - 2/7 + 2/7 = 1/3 + 2/7

x - 2/7 + 2/7 leaves x and 1/3 + 2/7 is 13/21 which means we end up with x = 13/21. Therefore, the answer to "What minus 2/7 equals 1/3?" is as follows:

13/21

It is always good to double-check your math to make sure you did it right. When we entered 13/21 for x in this equation x - 2/7 = 1/3, we get the following true equation which means our math is correct.

13/21 - 2/7 = 1/3
