Question

On the first day of school, the cafeteria serves hot dogs and hamburgers together. The cafeteria serves hot dogs every 6th school day and hamburgers every 4th school day for the rest of the year. If there are a total of 180 school days, how many times will the cafeteria serve hot dogs and hamburgers together this year?

Answer 1

Answer:

The Answer is 12 days or times.

Step-by-step explanation:

The LCM of 6 is 3 and 2, the LCM of 4 is 2 and 1, so we multiply 3 by 2 and 4 by 2 together to get 12, which is the number of days or times.
