What value divided by 5 equals 81?

In other words, what would the dividend be if the divisor were 5 and the quotient 81?

To find the answer, just multiply the divisor with the quotient: 5 × 81 = 405

To prove this, let's compute 405 divided by 5: 405 5 = 81

How does it work?

Asking which value divided by 5 gives a result of 81 is equivalent to solving the following equation:

x 5 = 81

  1. We need to isolate x, so multiply both sides by 5: 5 x 5 = 5 × 81
  2. 5 x 5 is equivalent to 5 5 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 5 × 81 = 405

So, if the divisor is 5 and the quotient is 81, the dividend is 405.
