Answer:
400 liters
Explanation:
To find the number of liters in a full tank, we can set up a proportion based on the information given.
We know that 20% of a full tank is equal to 80 liters. Let's represent the number of liters in a full tank as "x".
The proportion can be set up as follows:
20/100 = 80/x
To solve for x, we can cross multiply:
20x = 80 * 100
20x = 8000
Dividing both sides by 20:
x = 400
Therefore, there are 400 liters in a full tank
