What value divided by 20 equals 21?

In other words, what would the dividend be if the divisor were 20 and the quotient 21?

To find the answer, just multiply the divisor with the quotient: 20 × 21 = 420

To prove this, let's compute 420 divided by 20: 420 20 = 21

How does it work?

Asking which value divided by 20 gives a result of 21 is equivalent to solving the following equation:

x 20 = 21

  1. We need to isolate x, so multiply both sides by 20: 20 x 20 = 20 × 21
  2. 20 x 20 is equivalent to 20 20 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 20 × 21 = 420

So, if the divisor is 20 and the quotient is 21, the dividend is 420.
