Answer 3

Task 1: How much fabric is needed to make 12 identical dresses?

To find out how much fabric is needed to make 12 identical dresses, we can use the information given in the problem. It states that 28 meters of fabric were used to make 7 identical dresses.

To calculate the amount of fabric needed for 12 dresses, we can set up a proportion:

28 meters / 7 dresses = x meters / 12 dresses

To solve for x, we can cross-multiply and divide:

28 meters * 12 dresses = 7 dresses * x meters

336 meters = 7x

x = 336 meters / 7

x = 48 meters

Therefore, to make 12 identical dresses, 48 meters of fabric will be needed.

Task 2: How many dresses can be made from 60 meters of fabric?

To determine how many dresses can be made from 60 meters of fabric, we can use the information given in the problem. It states that 28 meters of fabric were used to make 7 identical dresses.

To calculate the number of dresses that can be made from 60 meters of fabric, we can set up a proportion:

28 meters / 7 dresses = 60 meters / x dresses

To solve for x, we can cross-multiply and divide:

28 meters * x dresses = 7 dresses * 60 meters

28x = 420

x = 420 / 28

x = 15

Therefore, 15 dresses can be made from 60 meters of fabric.
