28 does not have many factors so this is an easy question. So easy that I would think it would be just as easy to do it yourself as it was to type it in to wiki-answers. Maybe you did not understand the all the words in the question. so I will help you. The factor are
1,2,4, 7 ,14, and 28. Factor is another word for divisor. The reciprocals are 1,1/2,1/4,
1/7,1/14 and 1/28. I will let you add them up. Do not convert them to decimals,but convert them to all to the common denominator of 28 and see if you find anything interesting in your answer. If not, ask your teacher why she assigned the problem.
No. The answer depends on the context in terms of which the numbers are considered to be opposite.
