Final Answer:
To determine if a number is divisible by 2, we need to examine its units digit. Among the given options, the numbers 5638 are divisible by 2 based on the criterion of having an even units digit. Therefore, options 1 are the correct answers.
Step-by-step explanation:
To determine if a number is divisible by 2, we need to examine its units digit. If the units digit is even, the number is divisible by 2. Let's analyze the given options:
1) 5638 - Divisible by 2 (units digit is 8, an even number).
2) 4237 - Not divisible by 2 (units digit is 7, an odd number).
3) 2229 - Not divisible by 2 (units digit is 9, an odd number).
4) 6885 - Divisible by 2 (units digit is 5, an odd number).
Among the given options, the numbers 5638 are divisible by 2 based on the criterion of having an even units digit. Therefore, options 1 are the correct answers.
