Answer:
20 % are red
Step-by-step explanation:
I THINK this is what you mean:
24 blue + 6 red = 30 blocks total
6 red / 30 total = 6/30 = .2 = 20 %
You will need:
(2240/625)*250=896 ml of treatment liquid.
If each bottle contains 250 ml you'll need 3.6 bottles (3 bottles and a bit more than half a bottle).
I do not think you need the conversion 1 cubic meter=1000 litres unless the volume of the tank is in cubic meters BUT 2240 cubic meters seems too large!
