Brenda cuts her grass every 15 days and trims her shrubs every 24 days. if brenda cut her grass and trimmed her shrubs on june​ 1, how many days will it be before she cuts her grass and trims her shrubs on the same day​ again

Answer 1

To get the number of days that will pass before Brenda cuts her grass and shrubs on the same day will be found using least common multiple:
15=3×5
24=3×8
thus the LCM (24,15)=120 days
She will cut the grass again after 120 days
