51 times what equals 20?

51 times what equals 20? In other words, what do you multiply by 51 to get 20? If "x" is "what" in the sentence, "51 times what equals 20?", then the equation to solve the problem is as follows:

51 • x = 20

Which can be written as:

51x = 20

To solve the equation above, we need to remove the 51 on the left side to make the x alone. To do that, we divide both sides by 51.

51x/51 = 20/51

51x/51 is x and 20/51 is 0.3922 which means our equation will look like this:

x = 0.3922

Thus, the answer to "51 times what equals 20?" is 0.3922.

To double-check our work, multiply 0.3922 by 51 to see that it equals 20. (Note that our answer on this page is rounded to 4 digits if necessary.)
