Answer:
A
Step-by-step explanation:
4.22
3x2 is six. If you do that across, you would get 6/6 for both. 6/6 - 6/6 is how much?
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!
The rate of change for the graph would be the last option, 35. If you follow rise over run, you end up with a rise of 35 and a run of 1, or 35/1 which simplifies to 35.
To get the equivalent you have to half the denominator and the numerator so therefore it is 1/5 as you divide it by 2.
