you dont have to explain everything! just a little bit of explanation
and the answer

geerky42 · Answer

$\text{Every 2 days} \rightarrow \text{goes to the gym} \~\ \text{Every 5 days} \rightarrow \text{play tennis}$

So $LCM(2,5) = 10$ since because well... $10 = 2\times5$

So since she started on may 1st, she will do it again in next 10 days, which is May 11th

In next 10 day is May 21th. Another 10 days is May 31.
Does that help?
