Answer 2

Identifying and Classifying the Numbers

To classify the given numbers into two groups based on a certain criterion, we can use the property of even and odd numbers.

Even and Odd Numbers: - An even number is an integer that is exactly divisible by 2, leaving no remainder. - An odd number is an integer that is not exactly divisible by 2, leaving a remainder of 1.

Classifying the Numbers

Let's classify the given numbers into two groups based on whether they are even or odd:

- 54, 6, 78, 2, 37, 3, 26, 2, 69, 1, 34, 5, 62, 6, 75, 5

Even Numbers: - 54, 6, 78, 2, 26, 2, 34, 62, 6

Odd Numbers: - 37, 3, 69, 1, 5, 75, 5

Conclusion

Based on the classification, the even numbers are 54, 6, 78, 2, 26, 2, 34, 62, and 6, while the odd numbers are 37, 3, 69, 1, 5, 75, and 5.
