1.What is the difference between prime and composite numbers?Provide two examples
for each.
2. What is the difference between a factor and a multiple? Provide two examples of each.
3. Is the number 1 (prime, composite, or neither)? Explain your answer.
4. List all of the prime numbers 1-100.
5. Define least common denominator (LCD) and greatest common factor (GCF). Provide
two examples of each.
6. Find the LCD and GCF 27 and 45. EXPLAIN in detail how you found each answer.
7. Use your book or research on the internet. Help your group by listing divisibility rules.
How can tell if a number is divisible by 2, 3, 5, 6, 9, and 10?
8. What does it mean for a number to be "divisible" by another? Provide two examples.
9. If a number is divisible by another number, will it ever have a remainder? Provide two
examples of numbers that are NOT divisible by another. Make sure you indicate the
remainder (ex. 5 r 3- Use little r for the remainder in your answer.)
10. How will the GCF help you REDUCE fractions? Provide two examples.
11. In the next section of chapter 2, we will learn how to add and subtract fractions. To
add and subtract fractions, you must have the SAME number on the bottom parts of the
fractions. How will finding the LEAST COMMON DENOMINATOR be helpful in this process?
How will this help if we had to add 5/12 + 7/8? Explain your answer.
12. Find the prime factors of a) 76, b) 97, and c) 145, and d) 2,007. Explain how you got
