question 2!!! need help

Answer:
B -8 5/7, 8.1 bar, 8 3/4, 8 7/8
Step-by-step explanation:
8 3/4, -8 5/7, 8.1 bar, 8 7/8
from least to greatest
negative value -8 5/7 is the least
8 3/4 = (8*4 + 3) / 4 = 35/4 = 8.75
8.1 bar = 8.11111111111111.......
8 7/8 = (8*8 + 7) / 8 = 71/8 = 8.875
so the order is -8 5/7, 8.1 bar, 8 3/4, 8 7/8
