To classify each number as an integer or not, we need to understand the definition of an integer. An integer is a whole number (positive, negative, or zero) with no fractional or decimal parts.
1. 10: This number is a whole number with no decimal parts, so it is an integer.
2. -5: This number is also a whole number with no decimal parts, so it is an integer.
3. -16.42: This number has a decimal part, so it is not an integer. It is a decimal or a real number.
4. -5/6: This number is a fraction, but not a whole number. It has a fractional part, so it is not an integer. It is a rational number.
5. 27/7: Similar to the previous example, this number is a fraction with a fractional part. Thus, it is not an integer. It is also a rational number.
To classify a number, look for any fractional or decimal parts. If there are none, it is an integer. If there are decimal or fractional parts, it is not an integer.
