No. A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point. So, for example, 547 is a decimal number as well as an integer.
No.
No, 3.33 is not an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot have decimal or fractional parts. Since 3.33 has a decimal, it is classified as a rational number but not an integer.
No, 0.127 is not an integer. An integer is a whole number that can be positive, negative, or zero, but it does not include fractions or decimal points. Since 0.127 has a decimal component, it is classified as a rational number, not an integer.
No, 13.5 is not an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot have any fractional or decimal component. Since 13.5 contains a decimal, it is classified as a rational number, but not an integer.
No, -5.14 is not an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot have any fractional or decimal parts. Since -5.14 has a decimal component, it is classified as a rational number, not an integer.
No.
A fraction or a terminated decimal
3 is natural number, a whole number, an integer, a terminating decimal, and a rational number. It is not an irrational number.
No, 3.33 is not an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot have decimal or fractional parts. Since 3.33 has a decimal, it is classified as a rational number but not an integer.
An integer is a whole number. For instance, 1, 2, 3... There is no decimal part. So 23 is an integer. A rational number is a number that can be written as a/b. 23 can be written as 23/1, so 23 is a rational number. Thus, 23 is BOTH an integer and a rational number.
No, 0.127 is not an integer. An integer is a whole number that can be positive, negative, or zero, but it does not include fractions or decimal points. Since 0.127 has a decimal component, it is classified as a rational number, not an integer.
No, 13.5 is not an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot have any fractional or decimal component. Since 13.5 contains a decimal, it is classified as a rational number, but not an integer.
No, -5.14 is not an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot have any fractional or decimal parts. Since -5.14 has a decimal component, it is classified as a rational number, not an integer.
A rational number which is an integer can be simplified to a form in which the denominator is 1. That is not possible for a rational number which is not an integer.
9.0 is both an integer and a rational number. As an integer, it is a whole number without any fractional or decimal parts. As a rational number, it can be expressed as a fraction where the numerator is 9 and the denominator is 1, making it a ratio of two integers.
Whole number means the same thing as integer and does not have a fraction or decimal part. Rational numbers can be expressed as a ratio of whole numbers.
Every integer is a rational number.
