What is x when 39 divided by x equals 45?

In other words, what would the divisor be if the dividend were 39 and the quotient 45?

To find the answer, just divide the dividend by the quotient: 39 ÷ 45 = 0.86666666666667

To prove this, let's compute 39 divided by 0.86666666666667: 39 0.86666666666667 = 45

How does it work?

Asking what the value of x could be when 39 divided by x gives a result of 45, is equivalent to solving the following equation:

39 x = 45

  1. Multiply both sides by x: 39 x x = 45 x
  2. 39 x x is equivalent to x x × 39 , which simplifies to 1 × 39 (or just 39 ).
  3. Thus, the equation becomes: 39 = 45 x
  4. To find x, divide both sides by 45: 39 45 = 45 x 45
  5. Which gives, after simplification: 0.86666666666667 = x (or x = 0.86666666666667 )

So, if the dividend is 39 and the quotient is 45, the divisor is 0.86666666666667.
