Afactory can produce 100 bracelets every 15 minutes. how many bracelets can the factory produce in three and a half hours?

1,400 bracelets in 3 and a half hours

Step-by-step explanation:

First you have to find how many minutes are in 3 and a half hours. 1 hour is 60 minutes, so 60 + 60 + 60 is 3 hours or 180 minutes and 30 minutes is a half an hour. Therefore 3 and a half hours equals 210 minutes. Set up an equal proportion: 100 bracelets / 15 min = x bracelets / 210 min. Use algebra to solve: 100 * 210 = 15x → 21000 = 15x → 1400 = x.

1400 bracelets every 3.5 hours

Step-by-step explanation:

There are 60 minutes in an hour so

60/15=4

So, 100 times 4= 400

400 bracelets every hour.

400 times 3.5 (hours) = 1400

Hope this is very helpful for you!
