Question

Frank bought 3 gallons of gasoline. If he used ¾ of a gallon of gasoline, find the remaining amount of gasoline.
9/4
1/4
3/4
4/9

Answer 1

To determine the remaining amount of gasoline Frank has after using \( \frac{3}{4} \) of a gallon from the 3 gallons he initially bought, we can perform the following calculation:

1. Start with the total amount of gasoline: \( 3 \) gallons.
2. Subtract the amount of gasoline used: \( \frac{3}{4} \) gallon.

We start with the equation:

\[
\text{Remaining gasoline} = 3 - \frac{3}{4}
\]

To perform the subtraction, it's helpful to convert 3 into a fraction with a denominator of 4:

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

Now we can rewrite the equation:

\[
\text{Remaining gasoline} = \frac{12}{4} - \frac{3}{4}
\]

Now, we can subtract the two fractions:

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

Thus, the remaining amount of gasoline Frank has is \( \frac{9}{4} \) gallons.

So, the answer is:

\(\frac{9}{4}\)
