1 answer

To find the remaining amount of gasoline, we start with the amount of gasoline Frank bought and subtract the amount he used.

  1. Frank bought 3 gallons of gasoline.
  2. He used \( \frac{3}{4} \) of a gallon.

To find the remaining amount, we can perform the following calculation:

\[ 3 - \frac{3}{4} \]

We can convert 3 to a fraction with a denominator of 4:

\[ 3 = \frac{12}{4} \]

Now we can subtract:

\[ \frac{12}{4} - \frac{3}{4} = \frac{12 - 3}{4} = \frac{9}{4} \]

So the remaining amount of gasoline is \( \frac{9}{4} \) gallons.

The answer is \( \frac{9}{4} \).
