4 times what equals 87?

4 times what equals 87? In other words, what do you multiply by 4 to get 87? If "x" is "what" in the sentence, "4 times what equals 87?", then the equation to solve the problem is as follows:

4 • x = 87

Which can be written as:

4x = 87

To solve the equation above, we need to remove the 4 on the left side to make the x alone. To do that, we divide both sides by 4.

4x/4 = 87/4

4x/4 is x and 87/4 is 21.75 which means our equation will look like this:

x = 21.75

Thus, the answer to "4 times what equals 87?" is 21.75.

To double-check our work, multiply 21.75 by 4 to see that it equals 87. (Note that our answer on this page is rounded to 4 digits if necessary.)
