Answer:
0.871.
Step-by-step explanation:
if you divide 1/10 you get 0.1 and then you multiply it by 8 and you get 0.8
then you divide 1/100 and you get 0.01 then you multiply it by 7 and get 0.07
then you divide 1/1,000 and you get 0.001 then you multiply it by 1 and get 0.001 Now you add them together and get 0.8 + 0.07 + 0.001 = 0.871
