The ratio in the simplified form is
80:3
EXPLANATION
We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.
We obtain the ratio as follows:
[tex]20:0.75[/tex]
This is the same as
[tex]20: \frac{3}{4} [/tex]
We multiply each term in the ratio by 4 to obtain;
[tex]20 \times 4:0.75 \times 4[/tex]
This gives us,
[tex]80:3[/tex]
