Regrouping in addition, as in 64 + 43, involves adding numbers column by column from right to left. If the addition in a column results in a value of 10 or more, a 'carry over' or regrouping is done to the next column. The final resultant sum is 107.
To regroup when you find the sum of 64 + 43, you need to add the numbers column by column, moving from right (units) to left (tens, hundreds, etc.). In this case, add the right column (4 from 64 and 3 from 43) to get 7. Next, add the left column (6 from 64 and 4 from 43). The sum is 10. Since 10 is a two-digit number, the number in tens place (1) is carried over or regrouped to the tens column. To get the final answer, add the numbers in the tens column (including the carryover). This results in 107. In general, regrouping is a technique used in addition and subtraction to simplify calculations and solve problems more easily.

Answer: 4
The expression equivalent to 16a + 24b is 8(2a + 3b).
In order to determine which expression is equivalent, the expression has to be simplified. To do this, divide the two terms, by factors of both terms.
The factors of a number are numbers that divide the original number evenly.
Factors of 16 and 24 = 1, 2, 4, 6, 8
The expressions could be:
2(8a + 12b)
4(4a + 6b)
