Answer:
12.90
Step-by-step explanation:
The hundredth is the second decimal place.
Basically we want to drop the numbers after the 9.
12.89 <u>5</u>03
Use the underlined decimal place, right after what you are rounding to, to determine if you round up or down.
For numbers 0-4, round down (keep the number). For numbers 5-9, round up (increase by 1).
We need to round up because 5 is in the range 5-9.
"Add" 1 to the hundredth decimal place and treat it like addition:
. 12.89
<u>+ 0.01</u>
. 12.90
