What is x when 70 divided by x equals 21?

In other words, what would the divisor be if the dividend were 70 and the quotient 21?

To find the answer, just divide the dividend by the quotient: 70 ÷ 21 = 3.3333333333333

To prove this, let's compute 70 divided by 3.3333333333333: 70 3.3333333333333 = 21

How does it work?

Asking what the value of x could be when 70 divided by x gives a result of 21, is equivalent to solving the following equation:

70 x = 21

  1. Multiply both sides by x: 70 x x = 21 x
  2. 70 x x is equivalent to x x × 70 , which simplifies to 1 × 70 (or just 70 ).
  3. Thus, the equation becomes: 70 = 21 x
  4. To find x, divide both sides by 21: 70 21 = 21 x 21
  5. Which gives, after simplification: 3.3333333333333 = x (or x = 3.3333333333333 )

So, if the dividend is 70 and the quotient is 21, the divisor is 3.3333333333333.
