Jeremy has two 7 foot long boards. he needs to cut pieces that are 15 inches long from the boards. what is the greatest number of 15 inch pieces he can cut from the two boards ?

The most he could get is 5 pieces. 

Work
change 7 foot to inches which it 84
then you do
     84 divided by 15 you should get 5.6 

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)
