What value divided by 10 equals 81?

In other words, what would the dividend be if the divisor were 10 and the quotient 81?

To find the answer, just multiply the divisor with the quotient: 10 × 81 = 810

To prove this, let's compute 810 divided by 10: 810 10 = 81

How does it work?

Asking which value divided by 10 gives a result of 81 is equivalent to solving the following equation:

x 10 = 81

  1. We need to isolate x, so multiply both sides by 10: 10 x 10 = 10 × 81
  2. 10 x 10 is equivalent to 10 10 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 10 × 81 = 810

So, if the divisor is 10 and the quotient is 81, the dividend is 810.
