1/1 plus what equals 4/8?

Here we will show you how to calculate "what" in this sentence: "1/1 plus what equals 4/8?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

1/1 + x = 4/8

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

1/1 - 1/1 + x = 4/8 - 1/1

1/1 - 1/1 + x leaves x and 4/8 - 1/1 is -1/2 which means we end up with x = -1/2. Therefore, the answer to "1/1 plus what equals 4/8?" is as follows:

-1/2

It is always good to double-check your math to make sure you did it right. When we entered -1/2 for x in this equation 1/1 + x = 4/8, we get the following true equation which means our math is correct.

1/1 + -1/2 = 4/8
