What value divided by 81 equals 40?

In other words, what would the dividend be if the divisor were 81 and the quotient 40?

To find the answer, just multiply the divisor with the quotient: 81 × 40 = 3240

To prove this, let's compute 3240 divided by 81: 3240 81 = 40

How does it work?

Asking which value divided by 81 gives a result of 40 is equivalent to solving the following equation:

x 81 = 40

  1. We need to isolate x, so multiply both sides by 81: 81 x 81 = 81 × 40
  2. 81 x 81 is equivalent to 81 81 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 81 × 40 = 3240

So, if the divisor is 81 and the quotient is 40, the dividend is 3240.
