What is x when 15 divided by x equals 8?

In other words, what would the divisor be if the dividend were 15 and the quotient 8?

To find the answer, just divide the dividend by the quotient: 15 ÷ 8 = 1.875

To prove this, let's compute 15 divided by 1.875: 15 1.875 = 8

How does it work?

Asking what the value of x could be when 15 divided by x gives a result of 8, is equivalent to solving the following equation:

15 x = 8

  1. Multiply both sides by x: 15 x x = 8 x
  2. 15 x x is equivalent to x x × 15 , which simplifies to 1 × 15 (or just 15 ).
  3. Thus, the equation becomes: 15 = 8 x
  4. To find x, divide both sides by 8: 15 8 = 8 x 8
  5. Which gives, after simplification: 1.875 = x (or x = 1.875 )

So, if the dividend is 15 and the quotient is 8, the divisor is 1.875.
