Question

A 21-pound

turkey was cooked for a small banquet. The
caterer figures he will discard 5 pounds of bones and that
each person will eat 0.8 pounds of the remaining turkey. Hoy
many people will the turkey serve?

Answer 1

well, originally the turkey was 21 lbs, but the caterer is going to toss away 5 lbs of it, that leaves us with only 16 lbs for the guest, now each guest is going to eat 0.8 lbs, so how many times does 0.8 go into 16?

`16/ 0.8\implies \cfrac{16}{1}/ \cfrac{08}{10}\implies \cfrac{16}{1}/ \cfrac{4}{5}\implies \cfrac{16}{1}\cdot \cfrac{5}{4}\implies \cfrac{16}{4}\cdot \cfrac{4}{1}\implies 4\cdot 4\implies \text{\Large 16}`
