Final answer:
After converting 4 liters to approximately 1.056 gallons and adding it to the existing 3.5 gallons in the fish tank, the total volume of water will be about 4.556 gallons. Thus, Margo will not completely fill the 5-gallon fish tank with 4 liters of water.
Step-by-step explanation:
The question involves determining whether Margo will be able to completely fill her fish tank by adding 4 liters of water to it, where the fish tank currently contains 3.5 gallons and has a total capacity of 5 gallons. To answer this, we first need to convert the 4 liters into gallons since the fish tank's capacity is measured in gallons. We know that 1 gallon is approximately 3.79 liters, thus to convert liters to gallons, we divide the number of liters by 3.79:
4 L ÷ 3.79 L/gallon ≈ 1.056 gallons
When we add the 1.056 gallons to the existing 3.5 gallons already in the tank, we get:
3.5 gallons + 1.056 gallons = 4.556 gallons
Since the fish tank has a capacity of 5 gallons, and adding the 4 liters will result in a total of approximately 4.556 gallons, Margo will not be able to completely fill the tank with the 4 liters of water she has; she will still be short by roughly 0.444 gallons.
