Final answer:
To find the number of times more silkworms needed for a sheet compared to a scarf, divide the number of silkworms for the sheet by the number of silkworms for the scarf.
Step-by-step explanation:
To find the number of times more silkworms that are required to make a sheet compared to a scarf, we divide the number of silkworms needed for the sheet by the number of silkworms needed for the scarf.
Given that it requires 104 silkworms for a scarf and 1019 silkworms for a sheet, we can calculate:
1019 / 104 = 1019-4 = 1015
Therefore, the sheet requires 1015 times more silkworms than the scarf.
