81 times what equals 16?

81 times what equals 16? In other words, what do you multiply by 81 to get 16? If "x" is "what" in the sentence, "81 times what equals 16?", then the equation to solve the problem is as follows:

81 • x = 16

Which can be written as:

81x = 16

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 = 16/81

81x/81 is x and 16/81 is 0.1975 which means our equation will look like this:

x = 0.1975

Thus, the answer to "81 times what equals 16?" is 0.1975.

To double-check our work, multiply 0.1975 by 81 to see that it equals 16. (Note that our answer on this page is rounded to 4 digits if necessary.)
