Graded Quiz: Measurement What's the sum of 6 feet 10 inches and 8 feet 9 inches?

To find the sum of 6 feet 10 inches and 8 feet 9 inches, we can add the feet and inches separately. 1. **Add the feet:** \[ 6 \text{ feet} + 8 \text{ feet} = 14 \text{ feet} \] 2. **Add the inches:** \[ 10 \text{ inches} + 9 \text{ inches} = 19 \text{ inches} \] Now we have a total of 14 feet and 19 inches. Since there are 12 inches in a foot, we need to convert the 19 inches into feet and inches. 3. **Convert inches to feet:** \[ 19 \text{ inches} = 1 \text{ foot} + 7 \text{ inches} \quad (\text{since } 19 - 12 = 7) \] 4. **Add the converted feet to the total feet:** \[ 14 \text{ feet} + 1 \text{ foot} = 15 \text{ feet} \] So, the final sum is: \[ \text{Total} = 15 \text{ feet} 7 \text{ inches} \] Therefore, the sum of 6 feet 10 inches and 8 feet 9 inches is **15 feet 7 inches**.
