What value divided by 30 equals 21?

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

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

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

How does it work?

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

x 30 = 21

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

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