What is x when 15 divided by x equals 51?

In other words, what would the divisor be if the dividend were 15 and the quotient 51?

To find the answer, just divide the dividend by the quotient: 15 ÷ 51 = 0.29411764705882

To prove this, let's compute 15 divided by 0.29411764705882: 15 0.29411764705882 = 51

How does it work?

Asking what the value of x could be when 15 divided by x gives a result of 51, is equivalent to solving the following equation:

15 x = 51

  1. Multiply both sides by x: 15 x x = 51 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 = 51 x
  4. To find x, divide both sides by 51: 15 51 = 51 x 51
  5. Which gives, after simplification: 0.29411764705882 = x (or x = 0.29411764705882 )

So, if the dividend is 15 and the quotient is 51, the divisor is 0.29411764705882.
