Is 5.35
you add them and then you divide the nuber you get by 2 212+32=53 53/2=26.5
(21+53)/2 = 37
37

you add them and then you divide the nuber you get by 2 212+32=53 53/2=26.5
It is 51
57.5
50.Half-way number is 50.(53 - 47) / 2 = 347 + 3 = 5053 - 3 = 50* * * * *Is it not simpler just to do (47+53)/2 = 100/2 = 50
