Answer 2

Calculation of Silk Fabric in 8 Rolls

To calculate the amount of silk fabric in 8 rolls, we need to determine the length of silk fabric in one roll and then multiply it by 8.

Given information: - Length of three identical rolls of calico fabric: 78 m - Length of one roll of silk fabric is 4 m longer than the length of the calico fabric roll

Let's calculate the length of the silk fabric in one roll:

1. Determine the length of the calico fabric roll: - Length of three identical rolls of calico fabric: 78 m - Therefore, the length of one calico fabric roll is 78 m divided by 3: 26 m.

2. Determine the length of the silk fabric roll: - The silk fabric roll is 4 m longer than the calico fabric roll. - Therefore, the length of the silk fabric roll is 26 m + 4 m: 30 m.

3. Calculate the total length of silk fabric in 8 rolls: - Multiply the length of one silk fabric roll by 8: 30 m x 8 = 240 m.

Therefore, there are 240 meters of silk fabric in 8 rolls.
