What value divided by 15 equals 15?
In other words, what would the dividend be if the divisor were 15 and the quotient 15?
To find the answer, just multiply the divisor with the quotient: 15 × 15 = 225
To prove this, let's compute 225 divided by 15:
How does it work?
Asking which value divided by 15 gives a result of 15 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 15:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 15 and the quotient is 15, the dividend is 225.
