2- 5/5 an integer?
3- 485.84 an integer?
4 - -16/13 an integer?

Answer 1

Answers:

1. No, it is not an integer due to the decimal portion 0.17; integers are either positive or negative whole numbers. Zero is included as well.
2. Yes it is an integer because 5/5 = 1 which has no decimal or fractional parts.
3. No, it is not an integer for similar reasoning as problem 1. The 0.84 decimal portion is why we don't have an integer.
4. No, it is not an integer because -16/13 = -1.2308 approximately, and we don't have a negative whole number here.
