tim trung binh cong cua 1\2  3\4  4\5

Answer 1

=(1/2+3/4+4/5):3

=41/20:3

=41/60

Answer 2

Trung bình cộng (1/2 + 3/4+ 4/5 ) : 3 = 41/60

Answer 3

=(1/2+3/4+4/5):3

=41/20:3

=41/60

Answer 4

(  1/2 + 3/4+ 4/5) :3 = ( 10/20 + 15/20 + 16/20) :3

                             =           41/20                  : 3

                              =             41/20 x 1/3

                             = 41/60
