What is x when 31 divided by x equals 10?

In other words, what would the divisor be if the dividend were 31 and the quotient 10?

To find the answer, just divide the dividend by the quotient: 31 ÷ 10 = 3.1

To prove this, let's compute 31 divided by 3.1: 31 3.1 = 10

How does it work?

Asking what the value of x could be when 31 divided by x gives a result of 10, is equivalent to solving the following equation:

31 x = 10

  1. Multiply both sides by x: 31 x x = 10 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 = 10 x
  4. To find x, divide both sides by 10: 31 10 = 10 x 10
  5. Which gives, after simplification: 3.1 = x (or x = 3.1 )

So, if the dividend is 31 and the quotient is 10, the divisor is 3.1.
