First question.
[tex]-\frac{2}{6}<-2.6\text{ ?}[/tex]
we can see that
[tex]-\frac{2}{6}=-0.33[/tex]
however
[tex]-0.33>-2.6[/tex]
hence, the answer is false.
Second question.
[tex]-0.8<|-\frac{8}{10}|\text{ ?}[/tex]
this inequaltiy is equivalent to
[tex]-0.8<|-0.8|\text{ }[/tex]
however, |-0.8|=0.8. Therefore, the answer is true since 0.8 is greater than - 0.8.
3rd Question
[tex]\frac{9}{4}>-9.4[/tex]
the answer is true since positive number are greater than negative numbers.
