21 times what equals 79?

21 times what equals 79? In other words, what do you multiply by 21 to get 79? If "x" is "what" in the sentence, "21 times what equals 79?", then the equation to solve the problem is as follows:

21 • x = 79

Which can be written as:

21x = 79

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 = 79/21

21x/21 is x and 79/21 is 3.7619 which means our equation will look like this:

x = 3.7619

Thus, the answer to "21 times what equals 79?" is 3.7619.

To double-check our work, multiply 3.7619 by 21 to see that it equals 79. (Note that our answer on this page is rounded to 4 digits if necessary.)
