Acaterpillar is 2.83 centimeters long. how long i'd the caterpillar rounded to the nearest whole centimeter?
a. 2 centimeters
b. 2.8 centimeters
c. 2.9 centimeters
d. 3 centimeters
i think it is d. but i am not sure.

The answer to this is D because a whole is a number without decimal points or fractions. And since it is over .5 , you round up. So 3 centimeters.

D. would be the correct answer because a "whole" number is one without decimals. Whole numbers are NOT negative, so any number 0 and above without a decimal place is a whole number.

When rounding, take decimal places that are 5 or greater and make them 10. You can think of it as adding 1 to the number to the left of the rounded decimal place.

ex.  1.5 rounds up to 2
        the 5 becomes a 10 which turns the 1 into a 2
ex.  5.6 rounds to 6
       the 6 rounds up to 10 making the 5 a 6
ex.  9.2 rounds to 9
       because 2 is less than five it rounds down to 0

What is the inequality?
