Calculating Satin Fabric Required for Bedding Sets

To calculate the amount of satin fabric required for sewing 4 bedding sets, we can use the given information that 60 meters of satin fabric were used for sewing 3 bedding sets.

Given: - Satin fabric used for 3 bedding sets = 60 meters

Calculation

To find out how much satin fabric is needed for 4 bedding sets, we can use a simple proportion:

Let's denote the amount of satin fabric needed for 4 bedding sets as "x" meters.

We can set up the following proportion:

3 sets : 60 meters = 4 sets : x meters

Solving for x: x = (4 sets * 60 meters) / 3 sets x = 80 meters

Answer: So, 80 meters of satin fabric are needed for sewing 4 bedding sets.
