One watermelon serves about 20 people. If you want to have a picnic with 50 people, how many whole watermelons should you get? Assume you want as little left over as possible.



Answer :

3 watermelons 
1 = 20
2 = 40
3 = 60 

You would need 2.5 for an exact amount so you should get three if you have to use a whole number.
