6/9 minus what equals 1/5?
Here we will show you how to calculate "what" in this sentence: "6/9 minus what equals 1/5?" We start by making this word problem into an algebraic equation where "what" is the variable "x".
6/9 - x = 1/5
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 = 1/5 - 6/9
6/9 - 6/9 - x leaves -x and 1/5 - 6/9 is -7/15 which means we end up with -x = -7/15. Then, you multiply each side by -1 to get x = 7/15. Therefore, the answer to "6/9 minus what equals 1/5?" is as follows:
7/15
