2/1 times what equals 2/5?

Here we will show you how to calculate "what" in this sentence: "2/1 times what equals 2/5?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

(2/1) • (x) = (2/5)

To solve this equation, we want x alone on the left side of the equation so we start by dividing 2/1 on both sides like this:

((2/1) • (x)) / (2/1) = (2/5) / (2/1)

((2/1) • (x)) / (2/1) leaves x and (2/5) / (2/1) is 1/5 which means we end up with this x = 1/5. Therefore, the answer to "2/1 times what equals 2/5?" is as follows:

1/5

It is always good to double-check your math to make sure you did it right. When we entered 1/5 for x in this equation (2/1) • (x) = (2/5), we get the following true equation which means our math is correct.

(2/1) • (1/5) = (2/5)
