2/5 times what equals 3/8?

Here we will show you how to calculate "what" in this sentence: "2/5 times what equals 3/8?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

(2/5) • (x) = (3/8)

To solve this equation, we want x alone on the left side of the equation so we start by dividing 2/5 on both sides like this:

((2/5) • (x)) / (2/5) = (3/8) / (2/5)

((2/5) • (x)) / (2/5) leaves x and (3/8) / (2/5) is 15/16 which means we end up with this x = 15/16. Therefore, the answer to "2/5 times what equals 3/8?" is as follows:

15/16

It is always good to double-check your math to make sure you did it right. When we entered 15/16 for x in this equation (2/5) • (x) = (3/8), we get the following true equation which means our math is correct.

(2/5) • (15/16) = (3/8)
