1/6 minus what equals 4/7?

Here we will show you how to calculate "what" in this sentence: "1/6 minus what equals 4/7?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

1/6 - x = 4/7

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 1/6 on both sides like this:

1/6 - 1/6 - x = 4/7 - 1/6

1/6 - 1/6 - x leaves -x and 4/7 - 1/6 is 17/42 which means we end up with -x = 17/42. Then, you multiply each side by -1 to get x = -17/42. Therefore, the answer to "1/6 minus what equals 4/7?" is as follows:

-17/42

It is always good to double-check your math to make sure you did it right. When we entered -17/42 for x in this equation 1/6 - x = 4/7, we get the following true equation which means our math is correct.

1/6 - -17/42 = 4/7
