What value divided by 85 equals 21?
In other words, what would the dividend be if the divisor were 85 and the quotient 21?
To find the answer, just multiply the divisor with the quotient: 85 × 21 = 1785
To prove this, let's compute 1785 divided by 85:
How does it work?
Asking which value divided by 85 gives a result of 21 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 85:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 85 and the quotient is 21, the dividend is 1785.
