Answer 1

Answer:

-1/4 < -9/40 < 1/2 < 7/8 < 15/16

Step-by-step explanation:

-1/4     =   -0.2500

1/2      =   0.5000

7/8     =   0.8750

15/16  =   0.9375

-9/40 = -0.2250

therefore

-0.2500 < -0.2250 < 0.5000 < 0.8750 < 0.9375

hope it helps you..

Answer 2

Answer:

-1/4 < -9/40 < 1/2 < 7/8 < 15/16.

-1/4 = -0.2500

1/2 = 0.5000

7/8 = 0.8750

15/16=0.9375

-9/40=0.2250

-0.2500 < -0.2250 < 0.5000 < 0.8750 < 0.9375
