4/7 times what equals 2/1?

Here we will show you how to calculate "what" in this sentence: "4/7 times what equals 2/1?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

(4/7) • (x) = (2/1)

To solve this equation, we want x alone on the left side of the equation so we start by dividing 4/7 on both sides like this:

((4/7) • (x)) / (4/7) = (2/1) / (4/7)

((4/7) • (x)) / (4/7) leaves x and (2/1) / (4/7) is 3 1/2 which means we end up with this x = 3 1/2. Therefore, the answer to "4/7 times what equals 2/1?" is as follows:

3 1/2

It is always good to double-check your math to make sure you did it right. When we entered 3 1/2 for x in this equation (4/7) • (x) = (2/1), we get the following true equation which means our math is correct.

(4/7) • (3 1/2) = (2/1)
