Step-by-step explanation:You need to divide it.And first you change the mixed numbers 27 8/9 and 6 5/8 to improper fraction .27 8/9 as a improper fraction is 251/
9
. 6 5/8 as a improper fraction is 53/
8
.ANd now you divide 251/
9 by 53/
8.In order to divide fractions you need to do KCF which stand for Keep ,change,flip .SO you have 251/
9 divide 53/
8 ,now you KEEP 251/9 ,Change the division sign to multiplication ,and flip 53/8 to 8/53.And now you multiply 251/9 by 8/53 which gives you 2008/
477.Lastly you change 2008/
477 which is a improper fraction to a mixed number which is 4 100/477.
Lets approach this problem differently 15 gallons ....you drive ......330 miles lets divide both numbers by 15 to find out how much you can go with 1 gallon 1 gallon..... you drive.....330/15=22 you car goes 22 miles per 1 gallon if you put 20 gallons 20*22=440 miles
