2/9 plus what equals 3/8?

Here we will show you how to calculate "what" in this sentence: "2/9 plus what equals 3/8?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

2/9 + x = 3/8

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 2/9 on both sides like this:

2/9 - 2/9 + x = 3/8 - 2/9

2/9 - 2/9 + x leaves x and 3/8 - 2/9 is 11/72 which means we end up with x = 11/72. Therefore, the answer to "2/9 plus what equals 3/8?" is as follows:
