What value divided by 39 equals 21?

In other words, what would the dividend be if the divisor were 39 and the quotient 21?

To find the answer, just multiply the divisor with the quotient: 39 × 21 = 819

To prove this, let's compute 819 divided by 39: 819 39 = 21

How does it work?

Asking which value divided by 39 gives a result of 21 is equivalent to solving the following equation:

x 39 = 21

  1. We need to isolate x, so multiply both sides by 39: 39 x 39 = 39 × 21
  2. 39 x 39 is equivalent to 39 39 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 39 × 21 = 819

So, if the divisor is 39 and the quotient is 21, the dividend is 819.
