Question

My brother has a math question that he needs help on. I will give a medal to anyone who helps.
"On May 1, Louie had a science club meeting and a violin lesson. He has a science club meeting every 7 days and a violin lesson every 3 days. What is the next day he will have a science club meeting and a violin lesson on the same day?".
a) May 10
b) May 14
c) May 21
d) May 22

Answer 1

Since he has a science club meeting every 7 days and a violin lesson every 3 days and you want to know when they will have a science club meeting and a violin lesson on the same day, you find the LCD between 7 and 3, and that will be your day.

Answer 2

*LCM

Answer 3

That number would be 21.

So the next day he will have a science club meeting and a violin lesson on the same day will be May 21st.
