Dana find the sum 346 421 +152 for numbers 13a-13d, select yes or no to tell dana when to regroup 13a. regroup the ones _yes __ no 13b. add the regrouped ten _yes 13c. regroup the tens _yes 13d. add the regrouped hundred _yes

To add

    346
    421
+  152

Starting woth the ones place 6 + 1 + 2 = 9, because, the sum of the digits in the ones place is not upto 10, we will not regroup the ones place.

Thus, the answer to 13a is NO

Since, we did not regroup the ones place, there is no regrouped tens to add, thus the answer to 13b is NO.

Next, for the tens place, 4 + 2 + 5 = 11, because the sum of the digits in the ones place is upto 10, we regroup the tens place.

Thus, the answer to 13c is YES.

Since, we regrouped the ones place, we add the regrouped hundred, thus the answer to 13b is YES.

Finally, for the hundred place, 1 + 3 + 4 + 1 = 9

Therefore, the sum of

    346
    421
+  152

is 919
