Question

Classify each number as an integer or not

Answer 1

Answer: Yes-Yes-No-Yes-No

Explanation:

Integers are whole numbers, positive, negative or zero. They cannot be fractional or irrational numbers

-18/6 = -3, integer

26 = integer

3/2 = 1.5 = not an integer, not whole

79 = integer

-89.25 = not an integer, not whole

Answer 2

`\large\boxed{\tt\red{See \ Below.}}`

Explanation:

`\textsf{We are asked to identify whether or not a number is an integer.}`

`\large\underline{\textsf{What are Integers?}}`

`\textsf{Integers are only whole numbers that can be positive or negative.}`

`\underline{\textsf{Examples;}}`

`\textsf{35 is an Integer.}`

`\textsf{-2.5 is not an integer.}`

`\textsf{-27 is an integer.}`

`\tt -(4)/(5) \ \textsf{is not an Integer.}`

`\large\underline{\textsf{Solving;}}`

`\textsf{Let's identify the 5 numbers as integers, or not.}`

`\tt -(18)/(6) \ \textsf{is the same as -3, hence it's an integer. \boxed{\tt Yes.}}`

`\textsf{26 is an interger. \boxed{\tt Yes.}}`

`\tt (3)/(2) \ \textsf{is the same as 1.5, it's not an integer since it's not a whole number. \boxed{\tt No.}}`

`\textsf{79 is an integer. \boxed{\tt Yes.}}`

`\textsf{ -89.25 is not an integer, since it's not a whole number. \boxed{\tt No.}}`

`\textsf{They're integers since they are whole numbers. Others aren't since they're not.}`
