Answer

$-2, -\frac{7}{4}, \frac{1}{2},\sqrt 5, 2.4$

Work Step by Step

Turning all of the terms into decimals makes them easier to compare and arrange in ascending order. -2 as a decimal= -2.0 $-\frac{7}{4}$ as a decimal= -1.75 $\frac{1}{2}$ as a decimal= 0.5 $\sqrt 5$ as a decimal= 2.236 2.4 as a decimal= 2.4 $-2.0\lt-1.75\lt0.5\lt2.236\lt2.4$ After being arranged in ascending order, the correct answer is: $-2, -\frac{7}{4}, \frac{1}{2},\sqrt 5, 2.4$
