What is x when 9 divided by x equals 42?

In other words, what would the divisor be if the dividend were 9 and the quotient 42?

To find the answer, just divide the dividend by the quotient: 9 ÷ 42 = 0.21428571428571

To prove this, let's compute 9 divided by 0.21428571428571: 9 0.21428571428571 = 42

How does it work?

Asking what the value of x could be when 9 divided by x gives a result of 42, is equivalent to solving the following equation:

9 x = 42

  1. Multiply both sides by x: 9 x x = 42 x
  2. 9 x x is equivalent to x x × 9 , which simplifies to 1 × 9 (or just 9 ).
  3. Thus, the equation becomes: 9 = 42 x
  4. To find x, divide both sides by 42: 9 42 = 42 x 42
  5. Which gives, after simplification: 0.21428571428571 = x (or x = 0.21428571428571 )

So, if the dividend is 9 and the quotient is 42, the divisor is 0.21428571428571.
