Question

circle the even numbers: 2 8 9 15 90 13 100 3 22 14 50 104 201 46

Explanation:

Step1: Recall the definition of even numbers

An even number is an integer that is divisible by 2 with no remainder, i.e., if a number \( n \) satisfies \( n \div 2=\text{integer} \) (or \( n = 2k \) for some integer \( k \)).

Step2: Check each number

• \( 2\div2 = 1 \), so 2 is even.
• \( 8\div2=4 \), so 8 is even.
• \( 9\div2 = 4.5 \), not an integer, so 9 is odd.
• \( 15\div2=7.5 \), not an integer, so 15 is odd.
• \( 90\div2 = 45 \), so 90 is even.
• \( 13\div2 = 6.5 \), not an integer, so 13 is odd.
• \( 100\div2=50 \), so 100 is even.
• \( 3\div2 = 1.5 \), not an integer, so 3 is odd.
• \( 22\div2 = 11 \), so 22 is even.
• \( 14\div2=7 \), so 14 is even.
• \( 50\div2 = 25 \), so 50 is even.
• \( 104\div2=52 \), so 104 is even.
• \( 201\div2 = 100.5 \), not an integer, so 201 is odd.
• \( 46\div2=23 \), so 46 is even.

Answer:

The even numbers to circle are: 2, 8, 90, 100, 22, 14, 50, 104, 46
