81 times what equals 11?

81 times what equals 11? In other words, what do you multiply by 81 to get 11? If "x" is "what" in the sentence, "81 times what equals 11?", then the equation to solve the problem is as follows:

81 • x = 11

Which can be written as:

81x = 11

To solve the equation above, we need to remove the 81 on the left side to make the x alone. To do that, we divide both sides by 81.

81x/81 = 11/81

81x/81 is x and 11/81 is 0.1358 which means our equation will look like this:

x = 0.1358

Thus, the answer to "81 times what equals 11?" is 0.1358.

To double-check our work, multiply 0.1358 by 81 to see that it equals 11. (Note that our answer on this page is rounded to 4 digits if necessary.)
