To convert feet to inches, the correct approach is to multiply by the conversion factor that relates feet to inches. Since there are 12 inches in 1 foot, you would multiply the number of feet by 12 to get the equivalent measurement in inches.
So, the best option would be:
Converting feet to inches by multiplying 10 feet by 12 inches/1 foot.
This can be simplified to:
\(10 , \text{feet} \times \frac{12 , \text{inches}}{1 , \text{foot}} = 120 , \text{inches}\).
Here's how the other options stack up:
-
Converting feet to inches by dividing 10 feet by 12 inches/1 foot - This would give an incorrect answer.
-
Converting feet to inches by multiplying 11 feet by 1 foot/12 inches - This is not applicable since you should be converting from 10 feet, not 11 feet.
-
Converting feet to inches by multiplying 11 feet by 12 inches/1 foot - Again, this is not applicable since you should be converting from 10 feet, not 11 feet.
In conclusion, the correct and most logical conversion to use is to multiply 10 feet by the conversion factor of 12 inches per 1 foot.
