Is the number 42 divisible by 2?
To determine if 42 is divisible by 2, we apply the divisibility rule for 2:
According to the divisibility rule, a number is divisible by 2 if its last digit is one of the even digits: 0, 2, 4, 6, or 8.
Let's check the last digit of 42:
The last digit of 42 is 2.
The digit 2 is an even number.
Since 2 is even, it follows that 42 is divisible by 2.
Therefore, the answer to the problem is Yes, which corresponds to choice 1.
Yes
Is the number 43 divisible by 4?
The divisibility rule for 2 works because of place value! Since 10, 100, 1000, etc. are all divisible by 2, only the ones digit determines whether the entire number is even or odd.
Yes! Zero is an even number, so any number ending in 0 is automatically divisible by 2. For example, 30, 140, and 2000 are all divisible by 2.
You can divide, but the divisibility rule is much faster! With large numbers like 5,842, checking the last digit (2) is instant, while division takes more time.
The even digits are: 0, 2, 4, 6, and 8. If a number ends in any of these digits, it's divisible by 2. If it ends in 1, 3, 5, 7, or 9, it's not divisible by 2.
Yes! The rule works the same way. For example, -42 is also divisible by 2 because it ends in 2. The negative sign doesn't change the divisibility.
