What is x when 90 divided by x equals 7?

In other words, what would the divisor be if the dividend were 90 and the quotient 7?

To find the answer, just divide the dividend by the quotient: 90 ÷ 7 = 12.857142857143

To prove this, let's compute 90 divided by 12.857142857143: 90 12.857142857143 = 7

How does it work?

Asking what the value of x could be when 90 divided by x gives a result of 7, is equivalent to solving the following equation:

90 x = 7

  1. Multiply both sides by x: 90 x x = 7 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 = 7 x
  4. To find x, divide both sides by 7: 90 7 = 7 x 7
  5. Which gives, after simplification: 12.857142857143 = x (or x = 12.857142857143 )

So, if the dividend is 90 and the quotient is 7, the divisor is 12.857142857143.
