What value divided by 45 equals 21?

In other words, what would the dividend be if the divisor were 45 and the quotient 21?

To find the answer, just multiply the divisor with the quotient: 45 × 21 = 945

To prove this, let's compute 945 divided by 45: 945 45 = 21

How does it work?

Asking which value divided by 45 gives a result of 21 is equivalent to solving the following equation:

x 45 = 21

  1. We need to isolate x, so multiply both sides by 45: 45 x 45 = 45 × 21
  2. 45 x 45 is equivalent to 45 45 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 45 × 21 = 945

So, if the divisor is 45 and the quotient is 21, the dividend is 945.
