What is x when 31 divided by x equals 85?

In other words, what would the divisor be if the dividend were 31 and the quotient 85?

To find the answer, just divide the dividend by the quotient: 31 ÷ 85 = 0.36470588235294

To prove this, let's compute 31 divided by 0.36470588235294: 31 0.36470588235294 = 85

How does it work?

Asking what the value of x could be when 31 divided by x gives a result of 85, is equivalent to solving the following equation:

31 x = 85

  1. Multiply both sides by x: 31 x x = 85 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 = 85 x
  4. To find x, divide both sides by 85: 31 85 = 85 x 85
  5. Which gives, after simplification: 0.36470588235294 = x (or x = 0.36470588235294 )

So, if the dividend is 31 and the quotient is 85, the divisor is 0.36470588235294.
