81 times what equals 87?

81 times what equals 87? In other words, what do you multiply by 81 to get 87? If "x" is "what" in the sentence, "81 times what equals 87?", then the equation to solve the problem is as follows:

81 • x = 87

Which can be written as:

81x = 87

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 = 87/81

81x/81 is x and 87/81 is 1.0741 which means our equation will look like this:

x = 1.0741

Thus, the answer to "81 times what equals 87?" is 1.0741.

To double-check our work, multiply 1.0741 by 81 to see that it equals 87. (Note that our answer on this page is rounded to 4 digits if necessary.)
