Final answer:
To find the amount of water needed to fill the entire birdbath basin, set up a proportion and solve for X.
Step-by-step explanation:
To find the amount of water needed to fill the entire birdbath basin, we need to set up a proportion.
Let X represent the total amount of water needed to fill the birdbath basin.
We know that X gallons of water fills 3/5 of the basin.
So, we can set up the proportion:
X gallons / 1 basin = 3/5 gallons / 1 basin
Cross-multiplying, we get:
5X = 3
Dividing both sides by 5, we find that:
X = 3/5 gallons
