21 times what equals 85?

21 times what equals 85? In other words, what do you multiply by 21 to get 85? If "x" is "what" in the sentence, "21 times what equals 85?", then the equation to solve the problem is as follows:

21 • x = 85

Which can be written as:

21x = 85

To solve the equation above, we need to remove the 21 on the left side to make the x alone. To do that, we divide both sides by 21.

21x/21 = 85/21

21x/21 is x and 85/21 is 4.0476 which means our equation will look like this:

x = 4.0476

Thus, the answer to "21 times what equals 85?" is 4.0476.

To double-check our work, multiply 4.0476 by 21 to see that it equals 85. (Note that our answer on this page is rounded to 4 digits if necessary.)
