What is x when 90 divided by x equals 12?

In other words, what would the divisor be if the dividend were 90 and the quotient 12?

To find the answer, just divide the dividend by the quotient: 90 ÷ 12 = 7.5

To prove this, let's compute 90 divided by 7.5: 90 7.5 = 12

How does it work?

Asking what the value of x could be when 90 divided by x gives a result of 12, is equivalent to solving the following equation:

90 x = 12

  1. Multiply both sides by x: 90 x x = 12 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 = 12 x
  4. To find x, divide both sides by 12: 90 12 = 12 x 12
  5. Which gives, after simplification: 7.5 = x (or x = 7.5 )

So, if the dividend is 90 and the quotient is 12, the divisor is 7.5.
