Problem Analysis

We are given two rolls of fabric, one with a length of 240 meters and the other with a length of 120 meters. We need to determine how many costumes can be made using all the fabric, with each costume requiring 4 meters of fabric.

Solution 1: Division

One way to solve this problem is by dividing the total length of fabric by the length required for each costume. This will give us the total number of costumes that can be made.

Let's calculate the number of costumes using this method:

Total length of fabric = 240 meters + 120 meters = 360 meters Length required for each costume = 4 meters

Number of costumes = Total length of fabric / Length required for each costume

Substituting the values, we get:

Number of costumes = 360 meters / 4 meters = 90 costumes

Therefore, 90 costumes can be made using all the fabric.

Solution 2: Subtraction

Another way to solve this problem is by subtracting the length of fabric used for each costume from the total length of fabric until there is not enough fabric left to make another costume.

Let's calculate the number of costumes using this method:

Total length of fabric = 360 meters Length required for each costume = 4 meters

Number of costumes = 0 (initially)

While there is enough fabric to make another costume: - Subtract the length required for each costume from the total length of fabric - Increment the number of costumes by 1

After performing the calculations, we find that the number of costumes is 90, which matches the result obtained using the division method.

Conclusion

Using either method, we find that 90 costumes can be made using all the fabric.
