What is x when 15 divided by x equals 2?

In other words, what would the divisor be if the dividend were 15 and the quotient 2?

To find the answer, just divide the dividend by the quotient: 15 ÷ 2 = 7.5

To prove this, let's compute 15 divided by 7.5: 15 7.5 = 2

How does it work?

Asking what the value of x could be when 15 divided by x gives a result of 2, is equivalent to solving the following equation:

15 x = 2

  1. Multiply both sides by x: 15 x x = 2 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 = 2 x
  4. To find x, divide both sides by 2: 15 2 = 2 x 2
  5. Which gives, after simplification: 7.5 = x (or x = 7.5 )

So, if the dividend is 15 and the quotient is 2, the divisor is 7.5.
