Sure! Let's go through each question step by step.
1. Whenever you multiply or divide two numbers that are the same signs, the product/quotient will always be **a. positive**. Whenever you multiply or divide two numbers that have different signs, the product/quotient will always be **b. negative**.
- Correct Answers: **a and b**
2. The Commutative Property of Multiplication states that the order of multiplication does not change the product. Therefore, the correct answer is:
- **a. 9 × 4 = 4 × 9**
3. Determine the sign of each product:
1. -16 x 42 – **b. Negative** (one negative and one positive)
2. -5.5 x (-10) – **a. Positive** (both numbers are negative)
3. 305 x 200 – **a. Positive** (both numbers are positive)
4. 13 x (−12) – **b. Negative** (one positive and one negative)
- Correct Answers: **b, a, a, b**
4. Multiply: -28 x (-19). Both numbers are negative, so the product will be positive:
- Answer: **532**
5. Multiply 9.6 by 0.2:
- \( 9.6 \times 0.2 = 1.92 \)
- Answer: **1.92**
6. Multiply: 45 × −9. Since one number is negative, the product will be negative:
- \( 45 \times -9 = -405 \)
- They provided options:
- a. −7 15
- b. -8
- c. −4 45
- d. 7
- None of the options appear to represent the product accurately. The correct answer is **-405**.
7. Divide: −120 ÷ 24. Since one number is negative, the result will be negative:
- \( -120 ÷ 24 = -5 \)
- Correct Answer: **b. -5**
8. There are \( \frac{7}{8} \) cups of sugar in a canister in the kitchen. Ms. Johnson used \( \frac{1}{2} \) of the sugar when she baked a birthday cake.
- To find out how much sugar she used, you multiply \( \frac{7}{8} \) by \( \frac{1}{2} \):
\[
\frac{7}{8} \times \frac{1}{2} = \frac{7 \times 1}{8 \times 2} = \frac{7}{16}
\]
- Therefore, Ms. Johnson used \( \frac{7}{16} \) cups of sugar.
