Let's break this down question by question:
1. **What is the greatest common factor (GCF) of 36 and 84?**
- The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
- The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
- Common factors: 1, 2, 3, 4, 6, 12
- The greatest common factor is **12**.
2. **Laura has 16 pygmy goats and 28 dairy goats. How many goats will she put in each pen?**
- We need to find the GCF of 16 and 28.
- The factors of 16 are: 1, 2, 4, 8, 16
- The factors of 28 are: 1, 2, 4, 7, 14, 28
- Common factors: 1, 2, 4
- The greatest common factor is **4 goats**.
3. **Rewrite 135 + 45 in the form a(b + c) where a is the greatest common factor of 135 and 45.**
- The GCF of 135 and 45 is 45 (since 45 is the largest number that divides both).
- We can factor this as:
- \( 135 + 45 = 45(3 + 1) \)
- So the answer is **45 (3 + 1)**.
4. **Rewrite the numerical expression 36 + 54 using the distributive property:**
- The GCF of 36 and 54 is 18. Thus:
- \( 36 + 54 = 18(2 + 3) \)
- Also, we can show it using 9:
- \( 36 + 54 = 9(4 + 6) \)
- Correct options:
- **9 (4 + 6)** and **6 (6 + 9)** (as 9 is a factor of 36 and 54, while 6 as well.)
5. **Kylie read 5 ½ books and Brady read 6 ¼ books. How many books have they read together?**
- Convert to improper fractions or mixed numbers:
- \( 5 ½ = \frac{11}{2} \)
- \( 6 ¼ = \frac{25}{4} \)
- To add these, convert \( \frac{11}{2} \) to fourths: \( \frac{22}{4} \)
- Now add: \( \frac{22}{4} + \frac{25}{4} = \frac{47}{4} = 11 \frac{¾}{4} \)
- The answer is **11 ¾ books**.
6. **What is 0.15 equal to as a fraction?**
- \( 0.15 = \frac{15}{100} = \frac{3}{20} \)
7. **What is an equivalent fraction and decimal representation of 30%?**
- \( 30\% = \frac{30}{100} = \frac{3}{10}\)
- Decimal representation: \( 0.30 \)
8. **Which game was chosen by the greatest number of students?**
- Adopt Me: 0.25 of students
- Theme Park Tycoon: 1/2 = 0.50 of students
- Hide and Seek Extreme: 0.18 of students
- Dragon Adventures: 7% = 0.07 of students
- The greatest number of students chose **Theme Park Tycoon**.
