Question

for each number below, is it even or odd?
72
129
83

588
odd even

Explanation:

Step1: Determine for 72

A number is even if divisible by 2. \( 72 \div 2 = 36 \), so 72 is even. Mark Even for 72.

Step2: Determine for 129

\( 129 \div 2 = 64.5 \), not integer. So 129 is odd. Mark Odd for 129.

Step3: Determine for 83

\( 83 \div 2 = 41.5 \), not integer. So 83 is odd. Mark Odd for 83.

Step4: Determine for 25

\( 25 \div 2 = 12.5 \), not integer. So 25 is odd. Mark Odd for 25.

Step5: Determine for 588

\( 588 \div 2 = 294 \), integer. So 588 is even. Mark Even for 588.
