What minus 1/5 equals 2/8?

Here we will show you how to calculate "what" in this sentence: "What minus 1/5 equals 2/8?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x - 1/5 = 2/8

To solve this equation, we want x alone on the left side of the equation so we start by adding 1/5 on both sides like this:

x - 1/5 + 1/5 = 2/8 + 1/5

x - 1/5 + 1/5 leaves x and 2/8 + 1/5 is 9/20 which means we end up with x = 9/20. Therefore, the answer to "What minus 1/5 equals 2/8?" is as follows:

9/20

It is always good to double-check your math to make sure you did it right. When we entered 9/20 for x in this equation x - 1/5 = 2/8, we get the following true equation which means our math is correct.

9/20 - 1/5 = 2/8
