What plus 3/4 equals 2/8?

Here we will show you how to calculate "what" in this sentence: "What plus 3/4 equals 2/8?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x + 3/4 = 2/8

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 3/4 on both sides like this:

x + 3/4 - 3/4 = 2/8 - 3/4

x + 3/4 - 3/4 leaves x and 2/8 - 3/4 is -1/2 which means we end up with x = -1/2. Therefore, the answer to "What plus 3/4 equals 2/8?" 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 x + 3/4 = 2/8, we get the following true equation which means our math is correct.

-1/2 + 3/4 = 2/8
