What is x when 80 divided by x equals 15?

In other words, what would the divisor be if the dividend were 80 and the quotient 15?

To find the answer, just divide the dividend by the quotient: 80 ÷ 15 = 5.3333333333333

To prove this, let's compute 80 divided by 5.3333333333333: 80 5.3333333333333 = 15

How does it work?

Asking what the value of x could be when 80 divided by x gives a result of 15, is equivalent to solving the following equation:

80 x = 15

  1. Multiply both sides by x: 80 x x = 15 x
  2. 80 x x is equivalent to x x × 80 , which simplifies to 1 × 80 (or just 80 ).
  3. Thus, the equation becomes: 80 = 15 x
  4. To find x, divide both sides by 15: 80 15 = 15 x 15
  5. Which gives, after simplification: 5.3333333333333 = x (or x = 5.3333333333333 )

So, if the dividend is 80 and the quotient is 15, the divisor is 5.3333333333333.
