Answer 3

Task 1: Calculating the Total Length of Ribbon

To calculate the total length of ribbon, we need to add the lengths of the 5 pieces of ribbon and the additional 20 meters of ribbon that were purchased.

The total length of ribbon purchased is 5 meters + 20 meters = 25 meters.

Task 2: Calculating the Total Number of Ornaments

In one package, there are 186 ornaments of one type and 75 more ornaments of another type.

To calculate the total number of ornaments in the package, we need to add the number of ornaments of both types.

The total number of ornaments in the package is 186 + 75 = 261 ornaments.

Task 3: Calculating the Total Number of Seamstresses

In one workshop, there are 12 seamstresses, which is 9 fewer than the number of seamstresses in the second workshop.

To calculate the total number of seamstresses in both workshops, we need to add the number of seamstresses in each workshop.

Let's assume the number of seamstresses in the second workshop is x.

The total number of seamstresses in both workshops is 12 + x.

Please note that the exact number of seamstresses in the second workshop is not provided in the given information, so we cannot determine the exact total number of seamstresses without that information.
