6/9 minus what equals 1/1?

Here we will show you how to calculate "what" in this sentence: "6/9 minus what equals 1/1?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

6/9 - x = 1/1

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 6/9 on both sides like this:

6/9 - 6/9 - x = 1/1 - 6/9

6/9 - 6/9 - x leaves -x and 1/1 - 6/9 is 1/3 which means we end up with -x = 1/3. Then, you multiply each side by -1 to get x = -1/3. Therefore, the answer to "6/9 minus what equals 1/1?" is as follows:

-1/3

It is always good to double-check your math to make sure you did it right. When we entered -1/3 for x in this equation 6/9 - x = 1/1, we get the following true equation which means our math is correct.

6/9 - -1/3 = 1/1
