What value divided by 81 equals 1?
In other words, what would the dividend be if the divisor were 81 and the quotient 1?
To find the answer, just multiply the divisor with the quotient: 81 × 1 = 81
To prove this, let's compute 81 divided by 81:
How does it work?
Asking which value divided by 81 gives a result of 1 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 81:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 81 and the quotient is 1, the dividend is 81.
