What is x when 13 divided by x equals 31?

In other words, what would the divisor be if the dividend were 13 and the quotient 31?

To find the answer, just divide the dividend by the quotient: 13 ÷ 31 = 0.41935483870968

To prove this, let's compute 13 divided by 0.41935483870968: 13 0.41935483870968 = 31

How does it work?

Asking what the value of x could be when 13 divided by x gives a result of 31, is equivalent to solving the following equation:

13 x = 31

  1. Multiply both sides by x: 13 x x = 31 x
  2. 13 x x is equivalent to x x × 13 , which simplifies to 1 × 13 (or just 13 ).
  3. Thus, the equation becomes: 13 = 31 x
  4. To find x, divide both sides by 31: 13 31 = 31 x 31
  5. Which gives, after simplification: 0.41935483870968 = x (or x = 0.41935483870968 )

So, if the dividend is 13 and the quotient is 31, the divisor is 0.41935483870968.
