well...there's probly an elegant answer,
but here's a cheap one:
the smaalest number you have
is the Last one...which is actually 1/5 ... and you have
25 of them....which would equal '5' but if you change one to be
he first 1/1 it makes the sum greater than 5...to be exact:
1 & 24/5 or 1+4+ 4/5 = 5.8
