There are 3 whose sum is 45 whose sum is 57 whose sum is 69 whose sum is 711 whose sum is 813 whose sum is 915 whose sum is 1017 whose sum is 1119 whose sum is 1219 whose sum is 1317 whose sum is 1415 whose sum is 1513 whose sum is 1611 whose sum is 179 whose sum is 187 whose sum is 195 whose sum is 203 whose sum is 211 whose sum is 22.
1/2 + 1/3 + 1/6 is one example.
There is no pair of consecutive even integers whose sum is 264 - as their average is divisible by 4, that must mean that the sum of the unit digits of each of the pair of numbers could never be a multiple of 4 - which 264 is.
An algorithm for finding a unit fraction expression for any fraction is the Greedy Method. To use the Greedy Method on fraction X. Start with the largest unit fraction less then fraction X. Then continue in the same manner to represent the remaining value. 5/8th imperial measure or .625 in decimal.
1 + pi, 1 - pi. Their sum is 2.

The sum of a fraction? Well, to find the sum of the fraction all you do is divide both top and bottom numbers.
Yes. Although a negative fraction would have to involve addinig negative unit fractions. A positive fraction is a number of the form x/y where x and y are positive integers. The simplest solution is to add x lots of 1/y.
The two numbers whose sum is 58 and whose difference is 16 are 21 and 37.
There are infinitely many ways.
There are infinitely many different ways to make groups of fractions that sum to 1.
