What is x when 99 divided by x equals 90?

In other words, what would the divisor be if the dividend were 99 and the quotient 90?

To find the answer, just divide the dividend by the quotient: 99 ÷ 90 = 1.1

To prove this, let's compute 99 divided by 1.1: 99 1.1 = 90

How does it work?

Asking what the value of x could be when 99 divided by x gives a result of 90, is equivalent to solving the following equation:

99 x = 90

  1. Multiply both sides by x: 99 x x = 90 x
  2. 99 x x is equivalent to x x × 99 , which simplifies to 1 × 99 (or just 99 ).
  3. Thus, the equation becomes: 99 = 90 x
  4. To find x, divide both sides by 90: 99 90 = 90 x 90
  5. Which gives, after simplification: 1.1 = x (or x = 1.1 )

So, if the dividend is 99 and the quotient is 90, the divisor is 1.1.
