Brett asked George and Danielle to help him hang up 30 posters for a school dance. He gave 1/5 of the posters to george. He gave 1/3 of the remsoning posyers to danielle. Brett hung the remaining posters. How many posters did brett hang?

Posters hung by Brett are 16

Step-by-step explanation:

⇒ Posters hung by George = 1/5 of the 30 posters

                                              = 1/5 × 30 = 6

⇒ Remaining posters = 30 - 6 = 24

⇒ Posters hung by Danielle = 1/3 of 24 = 1/3 × 24 = 8

⇒ Posters hung by Brett = 30 - (6 + 8) = 30 - 14 = 16
