Avery gets newsletters by email! He gets one for sports every 5 days, one for model railroads every 10 days, and one for music every 8 days. If he got all three today , how many more days until he gets all three newsletters on the same day again?
Basically, just find a common denominator. The LCD of 8 and 10 is 40 and that is divisible by 5, too. So the answer is 40 days.
Answer:40
Step-by-step explanation:
To find when Avery will get all three mails of sports,model rail road&music again we need to find the LCM of
5,10,8
LCM of 5,10,8
5& 10 are multiples of 5 and thus we left with 1,2
and 2 & 8 are multiples of 2 thus we left with 1,4
and we get 40 as LCM
that is after 40 day Avery will get the three mails again on same day .
