Explain 2/2=1. write abother fraction that is equal to 1.

Division can be looked at as breaking things into parts. For example, with you 2 : 2 = 1 that can be looked at as you have two chocolate bars and 2 people who want those chocolate bars. How can you fairly give those 2 people 2 chocolate bars? Well you would give them 1 each? It'd be the same thing with 5 people and 5 chocolate bars. Any number divided by itself with always be one, no matter what. Unless you have 0/0 or infinity/infinity, but those are different scenarios.
