What value divided by 21 equals 19?

In other words, what would the dividend be if the divisor were 21 and the quotient 19?

To find the answer, just multiply the divisor with the quotient: 21 × 19 = 399

To prove this, let's compute 399 divided by 21: 399 21 = 19

How does it work?

Asking which value divided by 21 gives a result of 19 is equivalent to solving the following equation:

x 21 = 19

  1. We need to isolate x, so multiply both sides by 21: 21 x 21 = 21 × 19
  2. 21 x 21 is equivalent to 21 21 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 21 × 19 = 399

So, if the divisor is 21 and the quotient is 19, the dividend is 399.
