Question

4 or less let it rest 5 or more add one more

Answer 1

tenths is the first place after the decimal so we have to look at the hundredths place to determine if we need to round

2.839     3 is less  then 5 so leave it alone  2.8

2.764   6 is greater than 4  so 2.8

36.89   9 is greater than 4  so 36.9

1,534.739  4 is less than 5 so 1534.7
