What value divided by 19 equals 21?

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

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

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

How does it work?

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

x 19 = 21

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

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