4/13

4/13

Step-by-step explanation:

P( blackbeans) = number of cans of black beans

                           

                           total cans

                   =   4

                     

                       ( 4+6+3)

              = 4

                 

                 13

The greatest common factor of the 3 listed numbers, is 12.

This can be found by simply writing out all the factors of each number.
24's factors are: 1,2,3,4,6,8,12,24
