What is x when 56 divided by x equals 21?

In other words, what would the divisor be if the dividend were 56 and the quotient 21?

To find the answer, just divide the dividend by the quotient: 56 ÷ 21 = 2.6666666666667

To prove this, let's compute 56 divided by 2.6666666666667: 56 2.6666666666667 = 21

How does it work?

Asking what the value of x could be when 56 divided by x gives a result of 21, is equivalent to solving the following equation:

56 x = 21

  1. Multiply both sides by x: 56 x x = 21 x
  2. 56 x x is equivalent to x x × 56 , which simplifies to 1 × 56 (or just 56 ).
  3. Thus, the equation becomes: 56 = 21 x
  4. To find x, divide both sides by 21: 56 21 = 21 x 21
  5. Which gives, after simplification: 2.6666666666667 = x (or x = 2.6666666666667 )

So, if the dividend is 56 and the quotient is 21, the divisor is 2.6666666666667.
