Answer: least to greatest:
-26, -1.3, 0, 2.6, 6.5, 12
Explanation:
We can start by putting the negative numbers last (-26, -1.3) the greater a negative number is the smaller it actually is! so -26 would be the least followed by -1.3
0 would be after because well it's zero. then we can go least to greatest, 2.6, 6.5, 12.
