Answer:
30 days
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
