What is x when 31 divided by x equals 15?

In other words, what would the divisor be if the dividend were 31 and the quotient 15?

To find the answer, just divide the dividend by the quotient: 31 ÷ 15 = 2.0666666666667

To prove this, let's compute 31 divided by 2.0666666666667: 31 2.0666666666667 = 15

How does it work?

Asking what the value of x could be when 31 divided by x gives a result of 15, is equivalent to solving the following equation:

31 x = 15

  1. Multiply both sides by x: 31 x x = 15 x
  2. 31 x x is equivalent to x x × 31 , which simplifies to 1 × 31 (or just 31 ).
  3. Thus, the equation becomes: 31 = 15 x
  4. To find x, divide both sides by 15: 31 15 = 15 x 15
  5. Which gives, after simplification: 2.0666666666667 = x (or x = 2.0666666666667 )

So, if the dividend is 31 and the quotient is 15, the divisor is 2.0666666666667.
