What value divided by 15 equals 81?

In other words, what would the dividend be if the divisor were 15 and the quotient 81?

To find the answer, just multiply the divisor with the quotient: 15 × 81 = 1215

To prove this, let's compute 1215 divided by 15: 1215 15 = 81

How does it work?

Asking which value divided by 15 gives a result of 81 is equivalent to solving the following equation:

x 15 = 81

  1. We need to isolate x, so multiply both sides by 15: 15 x 15 = 15 × 81
  2. 15 x 15 is equivalent to 15 15 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 15 × 81 = 1215

So, if the divisor is 15 and the quotient is 81, the dividend is 1215.
