Answer:
2.
Step-by-step explanation:
To round off to the nearest whole number, we look at the tenth place value (the first digit after the decimal point.)
If it is a 0-4, we round the entire number down. If it is 5-9, we round the entire number up.
In this case, the tenth digit is 4. 4 is from the category 0-4, so we round 2.436 down to 2.
