Answer:
Polyester Fabric = 4 || 8 || 16 || 22
Silk Fabric = 18 || 36 || 72 || 99
Explanation:
Given:
The above table
Ratio; Polyester Fabric : Silk = 2:9
Required
Complete the above table
Provided that the ratio of the cost of one meter of polyester fabric to the cost of one meter of one silk is 2:9;
To complete rows of polyester fabric
We simply multiply cost by ratio of polyester fabric ratio (2)
To complete rows of silk fabric
We simply multiply cost by ratio of silk fabric ratio (9)
This is as follows:
When length = 2m
Polyester Fabric = 2 * 2 = 4
Silk Fabric = 2 * 9 = 18
When length = 4m
Polyester Fabric = 4 * 2 = 8
Silk Fabric = 4 * 9 = 36
When length = 8m
Polyester Fabric = 8 * 2 = 16
Silk Fabric = 8 * 9 = 72
When length = 11m
Polyester Fabric = 11 * 2 = 22
Silk Fabric = 11 * 9 = 99
Hence, the complete table is as follows:
Polyester Fabric = 4 || 8 || 16 || 22
Silk Fabric = 18 || 36 || 72 || 99
