Answer:
2.4 (2 2/5) pieces of pie per person.
Step-by-step explanation:
All that is needed to be done is simple division. Take your pieces of pie, (12) and divided it by the amount of people (5). This will give you 2.4. This can be turned into 24/10, and can be simplified twice. First to 12/5, then to 2 2/5.
Hope this helps!
If a square contains 171 tiles you will need multiply 21 by 171 (171x21) which should give you the amount for the entire roof.
Hope this helps! :)
