To regroup whole numbers, you need to borrow from a higher place value when performing subtraction or combine values from lower place values when adding. For example, in subtraction, if the digit in the minuend is smaller than the corresponding digit in the subtrahend, you can borrow 1 from the next higher place value, effectively adding 10 to the smaller digit. In addition, if the sum of a column exceeds 9, you carry over the extra value to the next higher place value. This process allows for accurate calculations while maintaining the integrity of the number system.
u just regroup the whole number ( ex. 7 would be 7 over 7)

yes you do, first you make the denominators the same, then you add the numerator after that you can regroup any "extras" into those whole numbers.
