Answer:
[tex]21\frac{1}{2}\ gallons[/tex]
Step-by-step explanation:
Convert mixed number to an improper fraction
[tex]16\frac{1}{8}\ gallons =\frac{16*8+1}{8}=\frac{129}{8}\ gallons[/tex]
remember that
[tex]\frac{3}{4}=0.75=75\%[/tex]
by proportion
[tex]\frac{(129/8)}{(75)}\frac{gallons}{\%} =\frac{x}{100}\frac{gallons}{\%} \\ \\x=100*(129/8)/75\\ \\x= \frac{129}{6}\ gallons\\ \\x=21\frac{1}{2}\ gallons[/tex]
