What value divided by 90 equals 87?
In other words, what would the dividend be if the divisor were 90 and the quotient 87?
To find the answer, just multiply the divisor with the quotient: 90 × 87 = 7830
To prove this, let's compute 7830 divided by 90:
How does it work?
Asking which value divided by 90 gives a result of 87 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 87, the dividend is 7830.
