Answer 2

Calculation of Fabric Sold in the Second Week

To calculate the amount of fabric sold in the second week, we need to first determine the amount of fabric remaining after the first week.

Given: - Total fabric in the store: 450 meters - Fabric sold in the first week: one-fifth (1/5) of the total fabric

To find the amount of fabric remaining after the first week, we subtract the fabric sold in the first week from the total fabric:

Fabric remaining after the first week = Total fabric - Fabric sold in the first week

Let's calculate the fabric sold in the first week:

Fabric sold in the first week = (1/5) * Total fabric

Substituting the given values:

Fabric sold in the first week = (1/5) * 450 meters = 90 meters Now, let's calculate the fabric remaining after the first week:

Fabric remaining after the first week = Total fabric - Fabric sold in the first week

Fabric remaining after the first week = 450 meters - 90 meters = 360 meters

Next, we need to find the fabric sold in the second week, which is one-third (1/3) of the remaining fabric.

Fabric sold in the second week = (1/3) * Fabric remaining after the first week

Substituting the calculated value of the fabric remaining after the first week:

Fabric sold in the second week = (1/3) * 360 meters

Now, let's calculate the fabric sold in the second week:

Fabric sold in the second week = (1/3) * 360 meters = 120 meters

Therefore, the amount of fabric sold in the store during the second week is 120 meters.
