What is x when 42 divided by x equals 40?

In other words, what would the divisor be if the dividend were 42 and the quotient 40?

To find the answer, just divide the dividend by the quotient: 42 ÷ 40 = 1.05

To prove this, let's compute 42 divided by 1.05: 42 1.05 = 40

How does it work?

Asking what the value of x could be when 42 divided by x gives a result of 40, is equivalent to solving the following equation:

42 x = 40

  1. Multiply both sides by x: 42 x x = 40 x
  2. 42 x x is equivalent to x x × 42 , which simplifies to 1 × 42 (or just 42 ).
  3. Thus, the equation becomes: 42 = 40 x
  4. To find x, divide both sides by 40: 42 40 = 40 x 40
  5. Which gives, after simplification: 1.05 = x (or x = 1.05 )

So, if the dividend is 42 and the quotient is 40, the divisor is 1.05.
