How can I solve this question number 17, from list the rational numbers in order from least to greatest

-2 4/5= -2.8
so now you are left with:
-2.3, -2.8(-2 4/5), -2.6
Since it is a negative number -2.3 would be greater than -2.6
so from least to greatest the order would go like this:
least to greatest
-2.8 (-2 4/5), -2.6, -2.3
Hope this helps! :3
