Divide bags of sand by gallons of water:
14 /6 = 2.33
21/9 = 2.33
The ratio is the same, so this means for every gallon of water you need 2.33 bags of sand.
Convert the fractions into decimals and you will get 7/3 = 2.33
The answer for Part 1 is D) 7/3
For part 2, multiply the gallons of water by 2.33 to get the number of sand bags needed:
12 x 2.33 = 27.99, which rounds to 28.
The answer is C) 28 bags.
