What value divided by 21 equals 30?

In other words, what would the dividend be if the divisor were 21 and the quotient 30?

To find the answer, just multiply the divisor with the quotient: 21 × 30 = 630

To prove this, let's compute 630 divided by 21: 630 21 = 30

How does it work?

Asking which value divided by 21 gives a result of 30 is equivalent to solving the following equation:

x 21 = 30

  1. We need to isolate x, so multiply both sides by 21: 21 x 21 = 21 × 30
  2. 21 x 21 is equivalent to 21 21 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 21 × 30 = 630

So, if the divisor is 21 and the quotient is 30, the dividend is 630.
