Question

select each number that is even.
55
78
32
166
101

Explanation:

Step1: Recall the definition of even numbers

An even number is an integer that is divisible by 2 with no remainder, or equivalently, an integer whose last digit is 0, 2, 4, 6, or 8.

Step2: Check each number

• For 55: The last digit is 5, so it is not divisible by 2. \( 55\div2 = 27.5 \), so 55 is odd.
• For 78: The last digit is 8. \( 78\div2 = 39 \), so 78 is even.
• For 32: The last digit is 2. \( 32\div2 = 16 \), so 32 is even.
• For 166: The last digit is 6. \( 166\div2 = 83 \), so 166 is even.
• For 101: The last digit is 1. \( 101\div2 = 50.5 \), so 101 is odd.

Answer:

78, 32, 166 (the corresponding options for these numbers should be selected)
