The following proportion could be used to change from gallons to which measure.


1 3 customary capacity:
- = - 1 Gallon=4 quarts
4 X 1 Gallon=128 fluid ounces
1 quart=2 pints
1 pint=2 cups
1 cup=8 fluid ounces

A. ounces
B. pints
C. quarts
D. gallons

Order the following number from least to greatest . 12.3

Quarts

To determine which measure this proportion could be used to change from gallons to, we need to identify the missing variable, which is represented by the letter "X" in the proportion:

1 / 4 = 3 / X

To solve for X, we can cross-multiply and then divide:

1 * X = 4 * 3
X = 12

Therefore, the missing measure is 12.

Now, let's determine which measure this corresponds to by looking at the information provided:

1 Gallon = 4 quarts
1 quart = 2 pints

Since we found that X = 12, and in the given information we have 1 quart = 2 pints, we can calculate:

12 pints = 6 quarts.

Looking at the answer choices:

A. ounces
B. pints
C. quarts
D. gallons

The correct answer is C. quarts. Using the given proportion, we can change from gallons to quarts.
