What value divided by 81 equals 21?

In other words, what would the dividend be if the divisor were 81 and the quotient 21?

To find the answer, just multiply the divisor with the quotient: 81 × 21 = 1701

To prove this, let's compute 1701 divided by 81: 1701 81 = 21

How does it work?

Asking which value divided by 81 gives a result of 21 is equivalent to solving the following equation:

x 81 = 21

  1. We need to isolate x, so multiply both sides by 81: 81 x 81 = 81 × 21
  2. 81 x 81 is equivalent to 81 81 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 81 × 21 = 1701

So, if the divisor is 81 and the quotient is 21, the dividend is 1701.
