Part 3/7:
So, the total number of marbles combined is 161. Therefore, our answer is that together, Eduardo and Renato have 161 marbles.
Second Problem: Food Donation
Moving on to our second problem, we are tasked with determining the total amount of food collected in a donation drive. Initially, the electronic board shows 3,695 kg of food, and an additional 349 kg is added.
Just as before, we read the problem closely to identify key details. The total shown is 3,695 kg, and there is a new donation of 349 kg. The term total indicates another addition.
We proceed to add the two quantities together:
3,695 kg + 349 kg involves attention to units, tens, hundreds, and thousands:
- Starting with the units: 5 + 9 equals 14 (write 4 and carry over 1).
