Let's solve each question step by step:
Question 1: We need to find the missing value when 4 inches is converted to centimeters. The conversion factor from inches to centimeters is 2.54.
So, for 4 inches: \[ 4 \text{ inches} \times 2.54 \text{ cm/inch} = 10.16 \text{ cm} \]
Answer: 10.16
Question 2: A) To find out how many times 5 inches is as big as 1 inch, we do the simple division: \[ \frac{5 \text{ inches}}{1 \text{ inch}} = 5 \]
B) To find out how many times 12.7 centimeters is as big as 2.54 centimeters, we perform the division: \[ \frac{12.7 \text{ cm}}{2.54 \text{ cm}} \approx 5 \]
Answer: 5 inches is 5 times as big as 1 inch.
12.7 centimeters is 5 times as big as 2.54 centimeters.
Question 3: From the relationship given in the question, we know: 5 yards = 15 feet, then:
- Using the conversions: \[ 15 \text{ yards} = 3 \times 15 \text{ feet} = 45 \text{ feet} \]
The missing value is therefore: Answer: 45
Question 4: To convert feet to inches, we know that 1 foot = 12 inches. Thus: \[ 8 \text{ feet} \times 12 \text{ inches/foot} = 96 \text{ inches} \]
Answer: 96 inches
Question 5: Without additional context, the exact error cannot be definitively identified. However, based on common errors in conversions:
The most likely option that represents a typical mistake could be: Answer: The student multiplied by 10 instead of 6.
This assumes that the error is commonly associated with conversion factors. Without more context this cannot be confirmed, so please verify the information provided for clarity.
