What value divided by 21 equals 51?

In other words, what would the dividend be if the divisor were 21 and the quotient 51?

To find the answer, just multiply the divisor with the quotient: 21 × 51 = 1071

To prove this, let's compute 1071 divided by 21: 1071 21 = 51

How does it work?

Asking which value divided by 21 gives a result of 51 is equivalent to solving the following equation:

x 21 = 51

  1. We need to isolate x, so multiply both sides by 21: 21 x 21 = 21 × 51
  2. 21 x 21 is equivalent to 21 21 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 21 × 51 = 1071

So, if the divisor is 21 and the quotient is 51, the dividend is 1071.
