Each tank goes for

12 \textrm{ gallons} \times \dfrac{22 \textrm{ miles}}{\textrm{gallon}} = 264 \textrm{ miles}

How many times he'll have to stop will be related to

\dfrac{638 \textrm{ miles}}{264 \textrm{ miles per tank}} = \dfrac{29}{12} = 2 \frac 5{12} \textrm{ tanks}

He started with a full tank so that means he'll have to fill up twice, once after 264 miles, once after twice that, 528 miles.

Find the difference between 7 1/2 and 2 3/4
NNADVOKAT [17]

Answer:

4\frac{3}{4} or 4.75

Step-by-step explanation:

first we're going to convert the number into improper fractions.

7\frac{1}{2}= \frac{15}{2} and 2\frac{3}{4}= \frac{11}{4}

For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply \frac{15}{2}x2, it'll equal the same number.

So now we have \frac{30}{4}-\frac{11}{4}, 30-11= 19.

\frac{19}4} simplified is, 4\frac{3}{4}.

As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.

I hope this helps you!
