What value divided by 20 equals 78?
In other words, what would the dividend be if the divisor were 20 and the quotient 78?
To find the answer, just multiply the divisor with the quotient: 20 × 78 = 1560
To prove this, let's compute 1560 divided by 20:
How does it work?
Asking which value divided by 20 gives a result of 78 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 20:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 20 and the quotient is 78, the dividend is 1560.
