What value divided by 21 equals 13?

In other words, what would the dividend be if the divisor were 21 and the quotient 13?

To find the answer, just multiply the divisor with the quotient: 21 × 13 = 273

To prove this, let's compute 273 divided by 21: 273 21 = 13

How does it work?

Asking which value divided by 21 gives a result of 13 is equivalent to solving the following equation:

x 21 = 13

  1. We need to isolate x, so multiply both sides by 21: 21 x 21 = 21 × 13
  2. 21 x 21 is equivalent to 21 21 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 21 × 13 = 273

So, if the divisor is 21 and the quotient is 13, the dividend is 273.
