Question

Maya mailed 3 packages. their weights were 4.5 lbs,2.75 lbs,and 3.4 lbs.

what was the total weight of the 3 packages.
question 2 is explain how u found the answer to the first question (only answer if you know the answer)​

Answer 1

The total weight was 10.65

Explanation: Since there is only one number in the hundredth place, i didn’t need to add. Instead i put that number as my hundredth place AKA 5. then i added the tenth place which was 5+7+4 which = 16. i carried the one over. then i added the ones place. 4+2+3= 9. the one i carried over got added to the 9. therefore my final answer was 10.65
