Nicole used a total of 5 1/6 gallons of gas while driving her car. Each hour she was driving, she used 5/9 gallons of gas what w
Gennadij [26K]

Let's write the total of gallons in improper fraction:

Step 1: Multiply the denominator by the whole number

6 × 5 = 30

Step 2: Add the answer from Step 1 to the numerator

30 + 1 = 31

Step 3: Write answer from Step 2 over the denominator

5 1/6  = 31 / 6

Let's divide the total gallons by what she used each hour to get the number of hours:

\dfrac{31}{6} \ : \ \dfrac{5}{9} = \dfrac{31}{6}\  \cdot \ \dfrac{9}{5} =  \dfrac{31}{2}\  \cdot \ \dfrac{3}{5} = \dfrac{93}{10}

Let convert the improper fraction to mixed number:

93/10 = 9 3/10

<h2>She was driven a total of 9 3/10 hours</h2>
