Answer:

2.75

Step-by-step explanation:

If Aleena's number is 2.8 when rounded to 1 decimal place, it means the actual number lies between 2.75 and 2.85, because when rounding to 1 decimal place, any number from 2.75 to 2.84 would round down to 2.8, and any number from 2.85 to 2.94 would round up to 2.9.

So, the smallest number Aleena could be thinking of that satisfies this condition is 2.75.
