Answer
$-0.8, .7/9, \sqrt 3$
Work Step by Step
In order to solve a problem ordering numbers from least to greatest, we want to try, if possible, to put all of the numbers in the same form. In this case, we will express them all as decimals. $\frac{7}{9}$=.777777..., and $\sqrt 3$=1.732...
1.732... is more positive than .777777...., and -.8 is the only negative number, making it less than the other two. Thus, in order from least to greatest, the numbers can be listed:
-0.8, .777777, 1.732
