Calculating Yarn Needed for Dresses and Sweaters

To calculate the amount of yarn needed for 4 dresses and 5 sweaters, given that 6.8 kg of yarn was used, we can use the following approach:

1. Calculate the total yarn used for the sweaters: - Given that 1 sweater requires 0.6 kg of yarn, the total yarn used for 5 sweaters can be calculated as: \[ 5 \times 0.6 = 3 \, \text{kg} \]

2. Calculate the total yarn used for the dresses: - To find the total yarn used for 4 dresses, we can subtract the total yarn used for the sweaters from the total yarn used: \[ 6.8 - 3 = 3.8 \, \text{kg} \]

3. Calculate the yarn needed for 1 dress: - Finally, to find the amount of yarn needed for 1 dress, we can divide the total yarn used for the dresses by the number of dresses: \[ \frac{3.8}{4} = 0.95 \, \text{kg} \]

Therefore, the amount of yarn needed for 1 dress is 0.95 kg.
