Question

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?

Answer 1

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 .

Answer 2

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.
