Calculation of Road Repairs

To calculate the portion of the road repaired during the third week, we need to determine the total length of the road and the amount repaired during the first two weeks.

Let's assume the total length of the road is x.

During the first week, 3/8 of the road was repaired. This means that 3/8 * x length of the road was repaired in the first week.

During the second week, 5/12 of the road was repaired. This means that 5/12 * x length of the road was repaired in the second week.

To find the portion of the road repaired during the third week, we need to subtract the lengths repaired in the first two weeks from the total length of the road:

x - (3/8 * x) - (5/12 * x)

Simplifying the expression:

x - (3/8 * x) - (5/12 * x) = x * (1 - 3/8 - 5/12)

To calculate the result, we need to find the common denominator for 8 and 12, which is 24:

x * (1 - 9/24 - 10/24) = x * (1 - 19/24) = x * (5/24)

Therefore, the portion of the road repaired during the third week is 5/24 of the total length of the road.

Please note that the specific length of the road is not provided in the question, so we cannot determine the exact length of the portion repaired during the third week.
