Question 1: The fraction that represents the ratio for the gallons of water to bags of sand is D) 7/3.
Question 2: To determine the number of bags of sand to mix with 12 gallons of water, we can use the ratio from the table. In this case, since the ratio is 6 gallons of water to 14 bags of sand, we can set up the following proportion:
6/14 = 12/x
Cross-multiplying, we get:
6x = 14 * 12
6x = 168
x = 168/6
x = 28
Therefore, the answer is C) 28 bags.
