3/9 minus what equals 1/8?


Here we will show you how to calculate "what" in this sentence: "3/9 minus what equals 1/8?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

3/9 - x = 1/8

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 3/9 on both sides like this:

3/9 - 3/9 - x = 1/8 - 3/9

3/9 - 3/9 - x leaves -x and 1/8 - 3/9 is -5/24 which means we end up with -x = -5/24. Then, you multiply each side by -1 to get x = 5/24. Therefore, the answer to "3/9 minus what equals 1/8?" is as follows:

5/24


It is always good to double-check your math to make sure you did it right. When we entered 5/24 for x in this equation 3/9 - x = 1/8, we get the following true equation which means our math is correct.

3/9 - 5/24 = 1/8
