What is x when 20 divided by x equals 5?

In other words, what would the divisor be if the dividend were 20 and the quotient 5?

To find the answer, just divide the dividend by the quotient: 20 ÷ 5 = 4

To prove this, let's compute 20 divided by 4: 20 4 = 5

How does it work?

Asking what the value of x could be when 20 divided by x gives a result of 5, is equivalent to solving the following equation:

20 x = 5

  1. Multiply both sides by x: 20 x x = 5 x
  2. 20 x x is equivalent to x x × 20 , which simplifies to 1 × 20 (or just 20 ).
  3. Thus, the equation becomes: 20 = 5 x
  4. To find x, divide both sides by 5: 20 5 = 5 x 5
  5. Which gives, after simplification: 4 = x (or x = 4 )

So, if the dividend is 20 and the quotient is 5, the divisor is 4.
