To check if distances can be a triangle add the smaller two distances together. If the sum is larger (not equal to) than the longest distance then it is a possible side. For example, 2,2,4 or 1,2,5cannot be a triangle, 2,3, 4 can be a triangle because 2+3 is greater than 4.
28/100=14/50=7/25 &the second one 2=200/100 so 200/100+65/100=265/100
265/100=53/20
