What is x when 18 divided by x equals 5?

In other words, what would the divisor be if the dividend were 18 and the quotient 5?

To find the answer, just divide the dividend by the quotient: 18 ÷ 5 = 3.6

To prove this, let's compute 18 divided by 3.6: 18 3.6 = 5

How does it work?

Asking what the value of x could be when 18 divided by x gives a result of 5, is equivalent to solving the following equation:

18 x = 5

  1. Multiply both sides by x: 18 x x = 5 x
  2. 18 x x is equivalent to x x × 18 , which simplifies to 1 × 18 (or just 18 ).
  3. Thus, the equation becomes: 18 = 5 x
  4. To find x, divide both sides by 5: 18 5 = 5 x 5
  5. Which gives, after simplification: 3.6 = x (or x = 3.6 )

So, if the dividend is 18 and the quotient is 5, the divisor is 3.6.
