Answer:
B. 
in decimal form, it would be 0.015625
<span> -5a^2-19a^2-5a-8+12a^2-22-14a-2a
first gather all same powers
-5a</span>²-19a²+12a²-5a-14a-2a-8-22
-12a²-21a-30
-3(6a²+7a-+10)
4/3 = 320/x
4x = 320*3
4x = 960
x = 240
Check:
320/240 divide both by 80
= 4/3 :)
The smallest number is 67/1000, then 0.672, then 68%, then 0.7, and the largest is 0.7
