Question

Is 12 a integer and is 55.3 a integer and is 18 over 2 a integer and is -260.43 a integer and is 12 over 17 a integer ?

Answer 1

Out of the given values, 12 and 9 (18 over 2) are integers, while 55.3, -260.43, and 12 over 17 are not integers because they include decimal parts or remain as fractions.

Step-by-step explanation:

The question asks whether certain values are integers. An integer is a whole number that can be positive, negative, or zero, but not a fraction or a decimal. Let's evaluate each value individually:

• 12 is an integer because it is a whole number without any fractional or decimal part.
• 55.3 is not an integer because it has a decimal part.
• 18 over 2, when simplified, becomes 9, which is an integer.
• -260.43 is not an integer because it has a decimal part.
• 12 over 17 cannot simplify evenly into a whole number; it remains a fraction, so it is not an integer.

Therefore, out of the values provided, 12 and 9 (18 divided by 2) are integers, while 55.3, -260.43, and 12/17 are not integers.

Answer 2

yes

no

yes

no

no

Step-by-step explanation:

An integer is a positive or negative whole number or zero.

Examples of integers:

-1000, 993, 12, -19, 1000000, -79, 0, 1, 221

Examples of numbers that are not integers:

-5/4, -223.25, 1000.1, 45.2, 1000000.45, 32/7

Is 12 a integer yes

and is 55.3 a integer no

and is 18 over 2 a integer = 9, so yes

and is -260.43 a integer no

and is 12 over 17 a integer =0.70588..., so no
