Answer:
24 days
Step-by-step explanation:
lowest common multiple of 12 and 8 is
24
For them to exercise together again, the day must be a common multiplier of 12 and 8
12 = [tex]2^{2} . 3[/tex]
8 = [tex]2^{3}[/tex]
So, their LCM is [tex]2^{3} .3 = 24[/tex]
=> After 24 days, they will exercise together again.
