What value divided by 9 equals 21?
In other words, what would the dividend be if the divisor were 9 and the quotient 21?
To find the answer, just multiply the divisor with the quotient: 9 × 21 = 189
To prove this, let's compute 189 divided by 9:
How does it work?
Asking which value divided by 9 gives a result of 21 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 9:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 9 and the quotient is 21, the dividend is 189.
