Final answer:
The sum of the numbers 613 and 712 is 1325. The numbers are added digit by digit from right to left, with the final sum being a four-digit number due to a carryover from the hundreds place.
Step-by-step explanation:
To add the numbers 613 and 712, we align the digits according to their place value and add them starting from the rightmost digit.
- Add the ones place: 3 + 2 = 5.
- Add the tens place: 1 + 1 = 2.
- Add the hundreds place: 6 + 7 = 13.
Combining them, we have the hundreds place as 13, the tens place as 2, and the ones place as 5. Therefore, the sum is 1325.
There are no denominators in this question to worry about, as both 613 and 712 are whole numbers, not fractions. To ensure our addition is correct, we can remember that the sum of two multi-digit numbers will have several digits equal to the largest number plus one if there's a carryover from the largest place value, which we have here with our sum of 1325. This eliminates the potential confusion suggested by some parts of the reference information, which pertain to adding fractions and significant figures - topics not relevant to this specific question.
