What is x when 80 divided by x equals 90?

In other words, what would the divisor be if the dividend were 80 and the quotient 90?

To find the answer, just divide the dividend by the quotient: 80 ÷ 90 = 0.88888888888889

To prove this, let's compute 80 divided by 0.88888888888889: 80 0.88888888888889 = 90

How does it work?

Asking what the value of x could be when 80 divided by x gives a result of 90, is equivalent to solving the following equation:

80 x = 90

  1. Multiply both sides by x: 80 x x = 90 x
  2. 80 x x is equivalent to x x × 80 , which simplifies to 1 × 80 (or just 80 ).
  3. Thus, the equation becomes: 80 = 90 x
  4. To find x, divide both sides by 90: 80 90 = 90 x 90
  5. Which gives, after simplification: 0.88888888888889 = x (or x = 0.88888888888889 )

So, if the dividend is 80 and the quotient is 90, the divisor is 0.88888888888889.
