2 and a half plus 2 and a half plus 10 plus 10 = 25
11/106 tenths plus one half:= 6/10 + 1/2= (6 + 5)/10= 11/10
Make it simpler by saying that five-tenths is one-half ... so you can rewrite it as what is seven and one-half plus ten and one-half? then you add 7 + 10 = 17 and one-half + one-half = one... .17+1=18 therefore 7 and 5/10 + 10 and 1/2 = 18
