What value divided by 21 equals 18?
In other words, what would the dividend be if the divisor were 21 and the quotient 18?
To find the answer, just multiply the divisor with the quotient: 21 × 18 = 378
To prove this, let's compute 378 divided by 21:
How does it work?
Asking which value divided by 21 gives a result of 18 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 21:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 21 and the quotient is 18, the dividend is 378.
