Answer:
29
Step-by-step explanation:
- Let's remember that the first number to the right of the decimal point is the "tenth".
- The first number to the left of the decimal point is the "ones"
- The second number to the left of the decimal point is the "tens"
In this problem we have the number 28.6 and we need to round it to the nearest ones.
To round to the nearest ones, we have to observe the tenths: in this case the tenth is a 6, this means that we will round it up (6,7,8 and 9 round up, and 1,2,3,4 and 5 round down).
Therefore, since the digit that corresponds to the ones is the 8, we will round it up to 9 and we obtain the number 29.
