Answer 3

To find out how long it will take the seamstress to sew 49 handkerchiefs, we can set up a proportion based on the given information:

The seamstress sews 21 handkerchiefs in 3 days, so the rate of her work is 21 handkerchiefs / 3 days = 7 handkerchiefs per day.

Now, let's use this rate to determine how many days it will take her to sew 49 handkerchiefs:

Number of days = Total handkerchiefs / Handkerchiefs per day Number of days = 49 handkerchiefs / 7 handkerchiefs per day Number of days = 7 days

So, the seamstress will take 7 days to sew 49 handkerchiefs.
