Brian has 3 basketball cards and 5 baseball cards. brian has 3 basketball cards and 5 baseball cards. what fraction of brian's cards are baseball cards?

Brian has 2/5 of 40 percent baseball cards.

Brainliest answer me pleasee

you have to add all the number of cards together so 3+5+5+3=16 
and only 10 out of 16 of the cards are baseball cards so it would be
                                                          10
                                                       
                                                           16     
if you simplify it is          5
                                       
                                           8
