Which of the following numbers is NOT divisible by 12?
Step 1: Understand what it means for a number to be divisible by 12. A number is divisible by 12 if it can be divided by 12 without leaving a remainder.
Step 2: To check if a number is divisible by 12, we need to check if it is divisible by both 3 and 4.
Step 3: Check if 55 is divisible by 3. To do this, add the digits of 55 (5 + 5 = 10). Since 10 is not divisible by 3, 55 is not divisible by 3.
Step 4: Check if 55 is divisible by 4. To do this, look at the last two digits of 55, which is 55. Since 55 divided by 4 equals 13 with a remainder of 3, 55 is not divisible by 4.
Step 5: Since 55 is not divisible by both 3 and 4, it is not divisible by 12.
