What value divided by 21 equals 28?

In other words, what would the dividend be if the divisor were 21 and the quotient 28?

To find the answer, just multiply the divisor with the quotient: 21 × 28 = 588

To prove this, let's compute 588 divided by 21: 588 21 = 28

How does it work?

Asking which value divided by 21 gives a result of 28 is equivalent to solving the following equation:

x 21 = 28

  1. We need to isolate x, so multiply both sides by 21: 21 x 21 = 21 × 28
  2. 21 x 21 is equivalent to 21 21 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 21 × 28 = 588

So, if the divisor is 21 and the quotient is 28, the dividend is 588.
