Explanation : Let the number is n, then its reciprocal is 1/n. Now, the sum of the numbers = n + 1/n = (n2 + 1)/n Now, from the options (a), when denominator n = 8 then, numerator should be (n)2 + 1 = (8)2 + 1 = 65 Option (b) when denominator n = 5 then, numerator should be n2 + 1 = 52 + 1 = 26. Hence, fraction is 26/5.
