Problem Analysis
To solve this problem, we need to determine the capacity of the second bucket in liters. We are given the following information: - The capacity of the first bucket is 2/3 of the capacity of the second bucket. - The capacity of the second bucket is 3/4 of the capacity of the third bucket. - The first bucket is filled to half of its capacity. - The second bucket is filled to 3/7 of its capacity. - The third bucket is filled to 1/14 of its capacity. - The total amount of water in the three buckets is 18 liters.Solution
Let's assume the capacity of the third bucket is x liters.According to the given information: - The capacity of the second bucket is 3/4 of x, which is (3/4)x liters. - The capacity of the first bucket is 2/3 of (3/4)x, which is (2/3)(3/4)x liters.
We are also given the following information about the amount of water in each bucket: - The first bucket is filled to half of its capacity, which is (1/2)(2/3)(3/4)x liters. - The second bucket is filled to 3/7 of its capacity, which is (3/7)(3/4)x liters. - The third bucket is filled to 1/14 of its capacity, which is (1/14)x liters.
The total amount of water in the three buckets is 18 liters, so we can set up the following equation:
(1/2)(2/3)(3/4)x + (3/7)(3/4)x + (1/14)x = 18
Now, let's solve this equation to find the value of x, which represents the capacity of the third bucket.
Calculation
To solve the equation, we can follow these steps:Step 1: Simplify the equation by multiplying the fractions: (1/2)(2/3)(3/4)x + (3/7)(3/4)x + (1/14)x = 18 (1/3)(3/4)x + (9/28)x + (1/14)x = 18
Step 2: Find a common denominator for the fractions: (7/7)(1/3)(3/4)x + (6/6)(9/28)x + (2/2)(1/14)x = 18 (7/12)x + (54/168)x + (1/14)x = 18
Step 3: Combine like terms: (7/12 + 54/168 + 1/14)x = 18 (98/168 + 54/168 + 12/168)x = 18 (164/168)x = 18
Step 4: Solve for x: (164/168)x = 18 x = (18 * 168)/164 x ≈ 18.54
The capacity of the third bucket is approximately 18.54 liters.
Answer
The capacity of the second bucket is 3/4 of the capacity of the third bucket, which is approximately (3/4) * 18.54 ≈ 13.91 liters. Therefore, the capacity of the second bucket is approximately 13.91 liters.
