2.6
Step-by-step explanation:
Using calculator, 10/3.9 =2.564
To the nearest tenth, we round the number after the tenth position.
If greater than 5 or equal to 5, we round to 1. if less than 5, we round to zero
Number after tenth place = 6
It is more than 5. so we round to 1
2.5 + 1 = 2.6
10÷3.9 to the nearest tenth = 2.6
