1

Step-by-step explanation:

1.09 is in between the whole numbers 1 and 2. it is closer to 1 since the tenths digit (0) is less than 5. if it were 5 or greater, then we would round up to 2.

Step-by-step explanation:

1.09 is closer to 1 than 2, therefore the whole number is 1.

If you were counting people or objects, well you can't have 9/100 as a person so you'd round to 2. But in this case, round to 1!

I hope this helped :)
