What value divided by 20 equals 81?
In other words, what would the dividend be if the divisor were 20 and the quotient 81?
To find the answer, just multiply the divisor with the quotient: 20 × 81 = 1620
To prove this, let's compute 1620 divided by 20:
How does it work?
Asking which value divided by 20 gives a result of 81 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 20:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 20 and the quotient is 81, the dividend is 1620.
