Q: If a number is divisible by 10, which of the following must be true?
Solution: A number divisible by 10 is always divisible by 2 and 5, and it is also even.
Steps: 4
Step 1: Understand what it means for a number to be divisible by 10. A number is divisible by 10 if it can be divided by 10 without leaving a remainder.
Step 2: Recognize that 10 can be broken down into its factors. The factors of 10 are 2 and 5 (since 10 = 2 x 5).
Step 3: If a number is divisible by 10, it must also be divisible by both of its factors, which are 2 and 5. This means that if a number can be divided by 10, it can also be divided by 2 and by 5 without leaving a remainder.
Step 4: Understand that a number is even if it is divisible by 2. Since any number divisible by 10 is also divisible by 2, it must be even.
