What is x when 69 divided by x equals 21?

In other words, what would the divisor be if the dividend were 69 and the quotient 21?

To find the answer, just divide the dividend by the quotient: 69 ÷ 21 = 3.2857142857143

To prove this, let's compute 69 divided by 3.2857142857143: 69 3.2857142857143 = 21

How does it work?

Asking what the value of x could be when 69 divided by x gives a result of 21, is equivalent to solving the following equation:

69 x = 21

  1. Multiply both sides by x: 69 x x = 21 x
  2. 69 x x is equivalent to x x × 69 , which simplifies to 1 × 69 (or just 69 ).
  3. Thus, the equation becomes: 69 = 21 x
  4. To find x, divide both sides by 21: 69 21 = 21 x 21
  5. Which gives, after simplification: 3.2857142857143 = x (or x = 3.2857142857143 )

So, if the dividend is 69 and the quotient is 21, the divisor is 3.2857142857143.
