Question

PLEASE HELP ASAP I NEED IT !!!

Ahmed and his brother went to the gym together today. Ahmed goes to the gym every 6 days and his brother goes to the gym every 9 days . After how many days will they go to the gym together again ?

Answer 1

18

Explanation:

To determine the number of days until they both work out at the gym on the same day again, Find the lowest common multiples of 6 days and 9 days.

Ahmed (6-days)=6,12,18,24

Brother(9-days)=9,18,24

Answer 2

After 18 days

Ahmed goes to the gym 3 times
6 • 3 = 18

His brother goes to the gym 2 times
9 • 2 = 18

Therefore… after 18 days Ahmed and his brother may go to the gym together again
