Answer:
2.6
Explanation:
the nearest tenth is located right where the 6 is in 2.643.
now you need to look at the number behind the 6→ 2.643.
if your numbers range from 1-4 then you round to zero
if your numbers range from 5-9 then you round up
2.643.
since the number behind the 6 is 4 then you round to zero
so 2.643 rounded to the nearest tenth is equal to 2.60 which is equal to 2.6
I hope this helped
