Final answer:
To find the weight of 2 loads of gravel, divide the total weight of 6 loads (2/3 ton) by 6 to determine the weight of one load (1/9 ton), then multiply by 2 to get 2/9 ton for 2 loads.
Step-by-step explanation:
To find the weight of 2 loads of gravel, when it is given that 6 loads weigh 2/3 ton, we should calculate the weight of one load first and then double that to get the weight of 2 loads.
To find the weight of one load, we divide the total weight by the number of loads:
2/3 ton ÷ 6 = 1/9 ton for one load of gravel.
Then, multiplying the weight of one load by 2 gives us the weight of two loads:
1/9 ton × 2 = 2/9 ton.
Therefore, the weight of 2 loads of gravel is 2/9 ton, which corresponds to answer choice D).
