Questions & Step-by-Step Solutions

Which of the following numbers is divisible by 9?
Correct Answer: 456
  • Step 1: Take the number you want to check for divisibility by 9. In this case, the number is 456.
  • Step 2: Add the digits of the number together. For 456, add 4 + 5 + 6.
  • Step 3: Calculate the sum. 4 + 5 + 6 equals 15.
  • Step 4: Check if the sum (15) is divisible by 9. To do this, see if 15 can be divided by 9 without a remainder.
  • Step 5: Since 15 divided by 9 equals 1 with a remainder of 6, 15 is not divisible by 9.
  • Step 6: Therefore, 456 is not divisible by 9.
