jamie volunteers at the pet shelter every 3 days and at the food pantry every 6 days. this month he volunteers at the pet shelte

denpristay [2]

Answer: No. Jamies reasoning doesn't make any sense.

Counter example :- Isha decides to go on walk on every 4th day and go for gym on every 2nd day in a month.

Then Isha will do both the things on same day = LCM (4,2)

Now, LCM of 4 and 2 = 4

Therefore, Isha will do both the things on 4th day of the month .

Step-by-step explanation:

Jamies reasoning doesn't make any sense.

Because the LCM of 3 and 6 = 6 not 18[since 6=3×2]

LCM is the least common multiple number of two or more numbers.
