Answer 3

Calculating Yarn Needed for Dresses and Sweaters

To find out how much yarn is needed for 1 dress, given that 6.8 kg of yarn was used for 4 dresses and 5 sweaters, and 0.6 kg of yarn was used for 1 sweater, we can use the following steps:

1. Calculate the total yarn used for the sweaters. 2. Calculate the total yarn used for the dresses. 3. Use the total yarn used for the dresses to find out how much yarn is needed for 1 dress.

Step 1: Calculate Total Yarn Used for Sweaters

We know that 0.6 kg of yarn was used for 1 sweater and there are 5 sweaters in total. Therefore, the total yarn used for the sweaters can be calculated as: - Total yarn for sweaters = 0.6 kg/sweater * 5 sweaters

Total yarn for sweaters = 3 kg

Step 2: Calculate Total Yarn Used for Dresses

We know that 6.8 kg of yarn was used for 4 dresses and 5 sweaters. To find out how much yarn was used for the dresses, we can subtract the total yarn used for the sweaters from the total yarn used for both dresses and sweaters: - Total yarn for dresses = Total yarn for dresses and sweaters - Total yarn for sweaters

Total yarn for dresses = 6.8 kg - 3 kg = 3.8 kg

Step 3: Calculate Yarn Needed for 1 Dress

To find out how much yarn is needed for 1 dress, we can divide the total yarn used for the dresses by the number of dresses: - Yarn needed for 1 dress = Total yarn for dresses / Number of dresses

Yarn needed for 1 dress = 3.8 kg / 4 dresses

Therefore, yarn needed for 1 dress = 0.95 kg.

So, based on the given information, 0.95 kg of yarn is needed for 1 dress.
