What is x when 40 divided by x equals 55?

In other words, what would the divisor be if the dividend were 40 and the quotient 55?

To find the answer, just divide the dividend by the quotient: 40 ÷ 55 = 0.72727272727273

To prove this, let's compute 40 divided by 0.72727272727273: 40 0.72727272727273 = 55

How does it work?

Asking what the value of x could be when 40 divided by x gives a result of 55, is equivalent to solving the following equation:

40 x = 55

  1. Multiply both sides by x: 40 x x = 55 x
  2. 40 x x is equivalent to x x × 40 , which simplifies to 1 × 40 (or just 40 ).
  3. Thus, the equation becomes: 40 = 55 x
  4. To find x, divide both sides by 55: 40 55 = 55 x 55
  5. Which gives, after simplification: 0.72727272727273 = x (or x = 0.72727272727273 )

So, if the dividend is 40 and the quotient is 55, the divisor is 0.72727272727273.
