If Sally eats cereal for breakfast 5 days in a row. She eats ham sandwich for 3 days in a row. She eats tacos 6 days in a row. She ate all three today. How many days till she will eat all three again?

30 days

Step-by-step explanation:

From the question, we know the following:

She eats cereal for breakfast 6 days in a row, she eats ham sandwich for 3 days in a row and tacos 6 days in a row.

Now, to find the number of days till she eat all three again, we simply find the lowest common multiples of the days

This means we find the lcm of 3,5 and 6

And this is equal 30 days
