What is x when 77 divided by x equals 20?

In other words, what would the divisor be if the dividend were 77 and the quotient 20?

To find the answer, just divide the dividend by the quotient: 77 ÷ 20 = 3.85

To prove this, let's compute 77 divided by 3.85: 77 3.85 = 20

How does it work?

Asking what the value of x could be when 77 divided by x gives a result of 20, is equivalent to solving the following equation:

77 x = 20

  1. Multiply both sides by x: 77 x x = 20 x
  2. 77 x x is equivalent to x x × 77 , which simplifies to 1 × 77 (or just 77 ).
  3. Thus, the equation becomes: 77 = 20 x
  4. To find x, divide both sides by 20: 77 20 = 20 x 20
  5. Which gives, after simplification: 3.85 = x (or x = 3.85 )

So, if the dividend is 77 and the quotient is 20, the divisor is 3.85.
