if 6 seamstresses can sew 15 skirts in 16 hours, how many skirts can 4 seamstresses sew in 8 hours?

Answer 1

Let's assume that the rate of sewing skirts is proportional to the number of seamstresses and the time spent sewing.

So, if 6 seamstresses can sew 15 skirts in 16 hours, then the rate is 15 skirts / (6 seamstresses * 16 hours) = 15/96 skirts per hour per seamstress.

Now, let's find the number of skirts 4 seamstresses can sew in 8 hours. We'll use the same rate:

= (15/96 skirts per hour per seamstress) * (4 seamstresses) * (8 hours)
= (15 * 4 * 8) / (96)
= 60/96
= 5/8 skirts

Therefore, 4 seamstresses can sew 5/8 of a skirt in 8 hours.
