A farmer is planting squash plants that need 2 3/8 feet to spread out. He has an area along a fence that is 20 feet long. Round the amount of space the squash plants need to the nearest 1/2 foot. How many squash plants can the farmer grow along the fence?
I assume plants spread 2 3/8 in all directions, so the space between must be twice that, and for 20 feet..
number plants=20/(4 6/8)=20/(38/8)=160/38 you do it.
I get 4 plants.
