What is x when 19 divided by x equals 87?

In other words, what would the divisor be if the dividend were 19 and the quotient 87?

To find the answer, just divide the dividend by the quotient: 19 ÷ 87 = 0.2183908045977

To prove this, let's compute 19 divided by 0.2183908045977: 19 0.2183908045977 = 87

How does it work?

Asking what the value of x could be when 19 divided by x gives a result of 87, is equivalent to solving the following equation:

19 x = 87

  1. Multiply both sides by x: 19 x x = 87 x
  2. 19 x x is equivalent to x x × 19 , which simplifies to 1 × 19 (or just 19 ).
  3. Thus, the equation becomes: 19 = 87 x
  4. To find x, divide both sides by 87: 19 87 = 87 x 87
  5. Which gives, after simplification: 0.2183908045977 = x (or x = 0.2183908045977 )

So, if the dividend is 19 and the quotient is 87, the divisor is 0.2183908045977.
