Order the numbers from least to greatest:
 $-1.2,\ 2\ \frac{1}{5},\ \frac{5}{2},\ -\frac{3}{2}$  

• $-\frac{3}{2},\ -1.2,\ 2\frac{1}{5},\ \frac{5}{2}$

• $-1.2,\ -\frac{3}{2},\ \ 2\frac{1}{5},\ \frac{5}{2}$

• $\frac{5}{2},\ 2\frac{1}{5},\ -1.2,\ -\frac{3}{2}\$

Use  $<,\ >,\ or\ =$  to compare.

 $-2.50$  ______ $-2\ \frac{3}{4}$
