What is x when 51 divided by x equals 30?

In other words, what would the divisor be if the dividend were 51 and the quotient 30?

To find the answer, just divide the dividend by the quotient: 51 ÷ 30 = 1.7

To prove this, let's compute 51 divided by 1.7: 51 1.7 = 30

How does it work?

Asking what the value of x could be when 51 divided by x gives a result of 30, is equivalent to solving the following equation:

51 x = 30

  1. Multiply both sides by x: 51 x x = 30 x
  2. 51 x x is equivalent to x x × 51 , which simplifies to 1 × 51 (or just 51 ).
  3. Thus, the equation becomes: 51 = 30 x
  4. To find x, divide both sides by 30: 51 30 = 30 x 30
  5. Which gives, after simplification: 1.7 = x (or x = 1.7 )

So, if the dividend is 51 and the quotient is 30, the divisor is 1.7.
