What value divided by 31 equals 81?
In other words, what would the dividend be if the divisor were 31 and the quotient 81?
To find the answer, just multiply the divisor with the quotient: 31 × 81 = 2511
To prove this, let's compute 2511 divided by 31:
How does it work?
Asking which value divided by 31 gives a result of 81 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 31:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 31 and the quotient is 81, the dividend is 2511.
