Which of the following numbers is an example of an integer?
A. square root of 5
B. Start Root 9 End Root
C. one-third
D. 0.8
0.8 is not an integer
√9 = 3 is an integer
The example of an integer among the given options is:
D. 0.8
An integer is a whole number that can be positive, negative, or zero. In this case, 0.8 is not an integer as it is a decimal or a fraction.
An integer is a whole number that can be positive, negative, or zero. It does not include fractions or decimals.
To determine which of the given numbers is an integer, you need to assess whether each option fits the definition. Let's go through each choice:
A. The square root of 5 is not an integer because it is an irrational number, meaning it cannot be expressed as a fraction or a finite decimal.
B. The square root of 9 is 3, which is a whole number. Therefore, option B is an example of an integer.
C. One-third is a fraction, not an integer. It represents a part of a whole and is not a complete number.
D. 0.8 is a decimal and, thus, not an integer.
In conclusion, the only example of an integer among the given choices is B. (Start Root 9 End Root).
