An aquarium holds 6 1/4 gallons of water. The water level has dropped to 4/5 of this amount. How much water should be added to fill the aquarium?

1 1/4

To find out how much water should be added to fill the aquarium, we need to subtract the current water level from the full capacity of the aquarium.

1. Start by converting 6 1/4 gallons to an improper fraction. Multiplying the whole number (6) by the denominator (4) and adding the numerator (1), we get: (6 × 4) + 1 = 24 + 1 = 25/4 gallons.

2. Next, calculate 4/5 of the full capacity to find the current water level. Multiply 25/4 by 4/5: (25/4) × (4/5) = (25 × 4) / (4 × 5) = 100/20 = 5/1 gallons.

3. Now, subtract the current water level from the full capacity to determine the amount of water that needs to be added. Subtract 5/1 from 25/4: (25/4) - (5/1) = 25/4 - 20/4 = 5/4 gallons.

Hence, to fill the aquarium, you need to add 5/4 gallons of water.

If the question read that the aquarium held 5 gallons of water and the water level had been reduced to 1/2 of that, How much water would be in it then? How did you figure that out? Now whats left to do is to subtract the amount you just got from 5 and that would be how much water is needed.

Do you think you can figure out how to do the problem now?

I need help with that too i know the answer but need the stupid work shown. So how do you show the work?
