What is x when 43 divided by x equals 20?

In other words, what would the divisor be if the dividend were 43 and the quotient 20?

To find the answer, just divide the dividend by the quotient: 43 ÷ 20 = 2.15

To prove this, let's compute 43 divided by 2.15: 43 2.15 = 20

How does it work?

Asking what the value of x could be when 43 divided by x gives a result of 20, is equivalent to solving the following equation:

43 x = 20

  1. Multiply both sides by x: 43 x x = 20 x
  2. 43 x x is equivalent to x x × 43 , which simplifies to 1 × 43 (or just 43 ).
  3. Thus, the equation becomes: 43 = 20 x
  4. To find x, divide both sides by 20: 43 20 = 20 x 20
  5. Which gives, after simplification: 2.15 = x (or x = 2.15 )

So, if the dividend is 43 and the quotient is 20, the divisor is 2.15.
