What is x when 8 divided by x equals 20?

In other words, what would the divisor be if the dividend were 8 and the quotient 20?

To find the answer, just divide the dividend by the quotient: 8 ÷ 20 = 0.4

To prove this, let's compute 8 divided by 0.4: 8 0.4 = 20

How does it work?

Asking what the value of x could be when 8 divided by x gives a result of 20, is equivalent to solving the following equation:

8 x = 20

  1. Multiply both sides by x: 8 x x = 20 x
  2. 8 x x is equivalent to x x × 8 , which simplifies to 1 × 8 (or just 8 ).
  3. Thus, the equation becomes: 8 = 20 x
  4. To find x, divide both sides by 20: 8 20 = 20 x 20
  5. Which gives, after simplification: 0.4 = x (or x = 0.4 )

So, if the dividend is 8 and the quotient is 20, the divisor is 0.4.
