What value divided by 13 equals 21?

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

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

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

How does it work?

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

x 13 = 21

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

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