2/6 plus what equals 2/5?

Here we will show you how to calculate "what" in this sentence: "2/6 plus what equals 2/5?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

2/6 + x = 2/5

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 2/6 on both sides like this:

2/6 - 2/6 + x = 2/5 - 2/6

2/6 - 2/6 + x leaves x and 2/5 - 2/6 is 1/15 which means we end up with x = 1/15. Therefore, the answer to "2/6 plus what equals 2/5?" is as follows:

1/15

It is always good to double-check your math to make sure you did it right. When we entered 1/15 for x in this equation 2/6 + x = 2/5, we get the following true equation which means our math is correct.

2/6 + 1/15 = 2/5
