Unlikely as 1/3 is about 33.33% and it’s less than 50% so chances are not that great.
Answer: 1 7/8
Step-by-step explanation:
Use 26/8 - 11/8 to get 15/8 then convert to mixed number
Check the picture below.
notice the sides, now, on the second triangle, side 6 slants a bit more to fit in 13, on the third triangle, side 6 slants even further to fit 13 in, now, if 6 were to slant completely, it'll make a flat-line with side 5, and there will be a triangle no more.
but even if side 6 would stretch to a flat-line, 5+6 is just 11, whilst side 13 is longer than that, so no dice.
4/156 so
2/78 so
1/39 so approx. 2.5641%
