Answer:
1110.0 units
Step-by-step explanation:
The balance reading is the sum of the readings on each of the scales:
100 +1000 +10 = 1110 . . . units
Expressed to the nearest tenth, this is ...
1110.0 units
(No units are shown on the balance scale, so we don't know if this is micrograms or tons or something in between.)
