81 times what equals 19?

81 times what equals 19? In other words, what do you multiply by 81 to get 19? If "x" is "what" in the sentence, "81 times what equals 19?", then the equation to solve the problem is as follows:

81 • x = 19

Which can be written as:

81x = 19

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 = 19/81

81x/81 is x and 19/81 is 0.2346 which means our equation will look like this:

x = 0.2346

Thus, the answer to "81 times what equals 19?" is 0.2346.

To double-check our work, multiply 0.2346 by 81 to see that it equals 19. (Note that our answer on this page is rounded to 4 digits if necessary.)
