78 times what equals 15?

78 times what equals 15? In other words, what do you multiply by 78 to get 15? If "x" is "what" in the sentence, "78 times what equals 15?", then the equation to solve the problem is as follows:

78 • x = 15

Which can be written as:

78x = 15

To solve the equation above, we need to remove the 78 on the left side to make the x alone. To do that, we divide both sides by 78.

78x/78 = 15/78

78x/78 is x and 15/78 is 0.1923 which means our equation will look like this:

x = 0.1923
