Answer 3

Calculation of Remaining Fabric

To calculate the remaining fabric, we need to determine the amount of fabric used in the first and second weeks.

Given: - Total fabric in the workshop: 300m - Fabric used in the first week: 2/5 of the total fabric - Fabric used in the second week: 4/9 of the remaining fabric after the first week

Let's calculate the fabric used in each week:

1. Fabric used in the first week: - 2/5 of the total fabric = (2/5) * 300m = 120m 2. Remaining fabric after the first week: - Total fabric - Fabric used in the first week = 300m - 120m = 180m

3. Fabric used in the second week: - 4/9 of the remaining fabric after the first week = (4/9) * 180m = 80m

Now, let's calculate the remaining fabric:

Remaining fabric = Remaining fabric after the first week - Fabric used in the second week = 180m - 80m = 100m

The remaining fabric in the workshop is 100 meters.

Please note that the calculations are based on the given information and assumptions.
