5 girls×9 days= 1 work

work done by 5 girls in a day= 1/9

work done by one girl per day= 1/(9×5)= 1/45

Therefore work done by 3 girls in a day

= 1/45 × 3

= 1/15

Let x be the number of days required to complete 1 work

1/15 ×x= 1

x= 15

therefore, three girls will take 15 days to embroider a dress.
