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
7/10 (seven tenths) Don't cheat. (:
1/2+3/8=7/8 -lover of math geeks ;) the common denominator is eight, so one half is converted into four eights. Then, three eighths plus four eighths is seven eighthts, so your answer is seven eighths. - A math geek
