Final answer:
The number that should be divided by 6831 to obtain a quotient of 21 with a remainder of 6 is 143457.
Step-by-step explanation:
To find the number that should be divided by 6831 to give a quotient of 21 and a remainder of 6, we can use the formula:
Dividend = (Divisor × Quotient) + Remainder
Let's plug in the values we know:
Dividend = (6831 × 21) + 6
Now, we perform the multiplication:
Dividend = 143451 + 6
Finally, we add the remainder to get:
Dividend = 143457
Therefore, the number we are looking for is 143457.
