What is x when 71 divided by x equals 21?

In other words, what would the divisor be if the dividend were 71 and the quotient 21?

To find the answer, just divide the dividend by the quotient: 71 ÷ 21 = 3.3809523809524

To prove this, let's compute 71 divided by 3.3809523809524: 71 3.3809523809524 = 21

How does it work?

Asking what the value of x could be when 71 divided by x gives a result of 21, is equivalent to solving the following equation:

71 x = 21

  1. Multiply both sides by x: 71 x x = 21 x
  2. 71 x x is equivalent to x x × 71 , which simplifies to 1 × 71 (or just 71 ).
  3. Thus, the equation becomes: 71 = 21 x
  4. To find x, divide both sides by 21: 71 21 = 21 x 21
  5. Which gives, after simplification: 3.3809523809524 = x (or x = 3.3809523809524 )

So, if the dividend is 71 and the quotient is 21, the divisor is 3.3809523809524.
