What is x when 90 divided by x equals 13?

In other words, what would the divisor be if the dividend were 90 and the quotient 13?

To find the answer, just divide the dividend by the quotient: 90 ÷ 13 = 6.9230769230769

To prove this, let's compute 90 divided by 6.9230769230769: 90 6.9230769230769 = 13

How does it work?

Asking what the value of x could be when 90 divided by x gives a result of 13, is equivalent to solving the following equation:

90 x = 13

  1. Multiply both sides by x: 90 x x = 13 x
  2. 90 x x is equivalent to x x × 90 , which simplifies to 1 × 90 (or just 90 ).
  3. Thus, the equation becomes: 90 = 13 x
  4. To find x, divide both sides by 13: 90 13 = 13 x 13
  5. Which gives, after simplification: 6.9230769230769 = x (or x = 6.9230769230769 )

So, if the dividend is 90 and the quotient is 13, the divisor is 6.9230769230769.
