What value divided by 80 equals 81?
In other words, what would the dividend be if the divisor were 80 and the quotient 81?
To find the answer, just multiply the divisor with the quotient: 80 × 81 = 6480
To prove this, let's compute 6480 divided by 80:
How does it work?
Asking which value divided by 80 gives a result of 81 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 80:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 80 and the quotient is 81, the dividend is 6480.
