What is x when 78 divided by x equals 28?

In other words, what would the divisor be if the dividend were 78 and the quotient 28?

To find the answer, just divide the dividend by the quotient: 78 ÷ 28 = 2.7857142857143

To prove this, let's compute 78 divided by 2.7857142857143: 78 2.7857142857143 = 28

How does it work?

Asking what the value of x could be when 78 divided by x gives a result of 28, is equivalent to solving the following equation:

78 x = 28

  1. Multiply both sides by x: 78 x x = 28 x
  2. 78 x x is equivalent to x x × 78 , which simplifies to 1 × 78 (or just 78 ).
  3. Thus, the equation becomes: 78 = 28 x
  4. To find x, divide both sides by 28: 78 28 = 28 x 28
  5. Which gives, after simplification: 2.7857142857143 = x (or x = 2.7857142857143 )

So, if the dividend is 78 and the quotient is 28, the divisor is 2.7857142857143.
