Homeroom 101 and homeroom 102 share a hallway bulletin board. If Homeroom 101 uses 3/5 of their half to display artwork, what fraction of the bulletin board is used to display Homeroom 101's artwork ???

Respuesta :

since you have 3/5 you need the other 5ths. 5/5 is a whole there for you can subtract 3/5 from 5/5. 5-3=2. 2/5+3/5=5/5
