Answer:
450L
Step-by-step explanation:
This is a ratio and proportion problem. First you need to determine the known ratio and the unknown ratio. In this case we have the known ratio:
[tex]\dfrac{20 lbs}{3L}[/tex]
The unknown ratio in this case is:
[tex]\dfrac{3,000lbs}{xL}[/tex]
So to do this, we just set up the proportion and solve for it:
[tex]\dfrac{20lbs}{3L}=\dfrac{3,000lbs}{xL}\\\\{20lbs}=\dfrac{3L\times3,000lbs}{xL}\\\\{xL}=\dfrac{3L\times3,000lbs}{20lbs}\\\\{xL}=\dfrac{9,000L}{20}\\\\xL = 450L[/tex]
