Answer:
12.9
Explanation:
The smallest possible answer for 4.48 + 8.56 would be obtained if we round down each number to the nearest tenth before adding them:
4.48 rounded down to the nearest tenth is 4.4
8.56 rounded down to the nearest tenth is 8.5
Adding these rounded numbers gives:
4.4 + 8.5 = 12.9
Therefore, the smallest possible answer for 4.48 + 8.56 is 12.9.
