First option because the (or) means the arrows aren’t connected and the open circle means not equal to and closed circle vice versa
Let x = 0.1515...
100x = 15.1515...
15.1515...
- 0.1515...
= 15
100x - x = 99x
99x = 15
X = 15/99
X is the short piece
(3•x-1)+x=31
4x=31+1
X=32/4=8
Short piece is 8
Long piece is 3•8-1=23
Check 8+23=31 ✔️
