What minus 4/5 equals 9/2?

Here we will show you how to calculate "what" in this sentence: "What minus 4/5 equals 9/2?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x - 4/5 = 9/2

To solve this equation, we want x alone on the left side of the equation so we start by adding 4/5 on both sides like this:

x - 4/5 + 4/5 = 9/2 + 4/5

x - 4/5 + 4/5 leaves x and 9/2 + 4/5 is 5 3/10 which means we end up with x = 5 3/10. Therefore, the answer to "What minus 4/5 equals 9/2?" is as follows:

5 3/10
