To determine which addition problem needs to be regrouped, we need to look for pairs of numbers whose sum exceeds 10. This is because when adding two numbers, if the sum is greater than 10, we need to regroup or carry over the extra value to the next place value.
Let's examine each addition problem:
A. 47 + 3: The sum is 50, so regrouping is not needed.
B. 32 + 7: The sum is 39, so regrouping is not needed.
C. 15 + 4: The sum is 19, so regrouping is not needed.
D. 11 + 8: The sum is 19, which exceeds 10. Therefore, regrouping is needed.
Therefore, the addition problem that needs regrouping to add is D. 11 + 8.
