What value divided by 21 equals 55?

In other words, what would the dividend be if the divisor were 21 and the quotient 55?

To find the answer, just multiply the divisor with the quotient: 21 × 55 = 1155

To prove this, let's compute 1155 divided by 21: 1155 21 = 55

How does it work?

Asking which value divided by 21 gives a result of 55 is equivalent to solving the following equation:

x 21 = 55

  1. We need to isolate x, so multiply both sides by 21: 21 x 21 = 21 × 55
  2. 21 x 21 is equivalent to 21 21 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 21 × 55 = 1155

So, if the divisor is 21 and the quotient is 55, the dividend is 1155.
