Let's go through each question step by step:
-
Which expression is equivalent to 0.8 x 0.6?
- To convert the decimals into fractions, we can express 0.8 as 8/10 and 0.6 as 6/10. Therefore, we can rewrite 0.8 x 0.6 as: \[ \frac{8}{10} \times \frac{6}{10} = \frac{8 \times 6}{10 \times 10} = \frac{48}{100} = 0.48 \]
- An equivalent expression in your options would be: \[ [8 \times \frac{1}{10}] \times [6 \times \frac{1}{10}] \]
- Answer: [8 x 1/10] x [6 x 1/10]

Chloe’s parents are buying carpeting for her room. The carpeting costs $3.28 per square foot, and the area is 96 square feet. How much will it cost?
- Total cost = cost per square foot × area \[ \text{Total cost} = 3.28 \times 96 = 314.88 \]
- Answer: $314.88

James bought a bag of dog food weighing 28.25 pounds. How many pounds would 2.5 bags weigh?
- Total weight = weight of one bag × number of bags \[ \text{Total weight} = 28.25 \times 2.5 = 70.625 \]
- Answer: 70.625 pounds
-
What is the total amount Ethan spent on his lunches?
- To find the total, we add the amounts for each day: \[ 5.25 + 6.48 + 4.95 + 7.22 + 5.96 \]
- Calculating step-by-step: \[ 5.25 + 6.48 = 11.73 \] \[ 11.73 + 4.95 = 16.68 \] \[ 16.68 + 7.22 = 23.90 \] \[ 23.90 + 5.96 = 29.86 \]
- Total amount spent = $30.86.
-
Will the actual product of 15.6 x 2.8 be greater or less than?
- Assuming you meant to ask if it will be greater or less than some number, you should calculate: \[ 15.6 \times 2.8 \]
- Performing this calculation: \[ 15.6 \times 2.8 = 43.68 \]
- Thus, whether it is greater or less depends on the number you are comparing it to. It is likely greater than or less than any specific number to be mentioned.
