What value divided by 90 equals 9?
In other words, what would the dividend be if the divisor were 90 and the quotient 9?
To find the answer, just multiply the divisor with the quotient: 90 × 9 = 810
To prove this, let's compute 810 divided by 90:
How does it work?
Asking which value divided by 90 gives a result of 9 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 90:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 90 and the quotient is 9, the dividend is 810.
