Answer:
[tex]44\ gallons[/tex]
Step-by-step explanation:
we know that
A fish tank holds [tex]80[/tex] gallons of water
so
By proportion
Find how many gallons represent [tex]55\%[/tex] of the total tank capacity.
[tex]\frac{80}{100}\frac{gallons}{\%} = \frac{x}{55}\frac{gallons}{\%}\\ \\x=55*80/100\\x= 44\ gallons[/tex]
