What is x when 90 divided by x equals 3?

In other words, what would the divisor be if the dividend were 90 and the quotient 3?

To find the answer, just divide the dividend by the quotient: 90 ÷ 3 = 30

To prove this, let's compute 90 divided by 30: 90 30 = 3

How does it work?

Asking what the value of x could be when 90 divided by x gives a result of 3, is equivalent to solving the following equation:

90 x = 3

  1. Multiply both sides by x: 90 x x = 3 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 = 3 x
  4. To find x, divide both sides by 3: 90 3 = 3 x 3
  5. Which gives, after simplification: 30 = x (or x = 30 )

So, if the dividend is 90 and the quotient is 3, the divisor is 30.
