Calculating the Number of Curtains from Each Piece of Fabric

To find out how many curtains were made from each piece of fabric, we can use the information provided about the amount of fabric in each piece and the total number of curtains made.

Let's calculate the number of curtains made from each piece of fabric.

From the first piece of fabric: - Amount of fabric = 28 meters - Number of curtains made = 12

From the second piece of fabric: - Amount of fabric = 20 meters - Number of curtains made = 12

Calculation:

To find out how many curtains were made from each piece of fabric, we can use the following formula: \[ \text{Number of curtains} = \frac{\text{Amount of fabric}}{\text{Fabric used per curtain}} \]

From the first piece of fabric: \[ \text{Number of curtains from first piece} = \frac{28}{12} = 2.33 \]

From the second piece of fabric: \[ \text{Number of curtains from second piece} = \frac{20}{12} = 1.67 \]

Conclusion:

- From the first piece of fabric: Approximately 2 curtains were made. - From the second piece of fabric: Approximately 2 curtains were made.

So, approximately 2 curtains were made from each piece of fabric.
