Does this question have the following choices?
A) 9 tanks 
B) 4 tanks 
C) 36 tanks 
D) 4.5 tanks
If so, then the answer would be letter D.
one tank has 36 m3 of fluid, which covers 2 shifts.
 Divide the number of shifts needed  by the number shifts each tank fills 
9 shifts needed ÷ 2 shifts each tank fills
= 4.5
4.5 Tanks, assuming you got it from USATESTPREP since that's what i got
