The following proportion could be used to change from feet to which measure.
1/12 = 2/x
customary length:
1 mile=1760 yards
1 mile=1285280 feet
1 yard=3 feet
1 foot=12 inches
A. ounces
B. pints
C. quarts
D. gallons
To determine the measure that can be used to convert feet, we need to solve the given proportion:
1/12 = 2/x
To solve for x, we can cross-multiply:
1x = 12 * 2
x = 24
Now, we look at the options provided (ounces, pints, quarts, and gallons) to see which one can be used to convert feet.
Among the given options, none of them directly correspond to measures of length. Therefore, none of these options can be used to convert feet.
Hence, the answer is none of the above options - none of them can be used to convert feet.
