Question

Miss Teo goes to the gym once every 4 days while Miss Nessa goes to the same gym once every 5 days. They first met each other at the gym on a Thursday. On which day of the week would they meet for the second time?

Answer 1

I got it first find the lcm of 4 and 5 and that is 20. Then find the next number that is both a multiple of 4 and 5 and that will be 40. So, you have to add 20 days and that will be Wednesday.

Answer 2

Well, this problem requires you to find the least common multiple of 4 and 5. Once you do that you find yourself with an answer of 20. So you add 20 days to that Thursday...and you get a Wednesday a couple weeks later.
