Final answer:
To find out how much gas is left in Susan's car, subtract the amount of gas she used from the total amount in her gas tank. The remaining gas is 2 10/9 gallons.
Step-by-step explanation:
To find out how much gas is left in Susan's car, we need to subtract the amount of gas she used from the total amount in her gas tank.
Susan's gas tank holds 12 4/9 gallons of gasoline. She used 10 2/3 gallons for her trip.
To subtract these fractions, we need to have a common denominator. The least common denominator for 9 and 3 is 9. So, we need to convert 4/9 to an equivalent fraction with a denominator of 9. That gives us 8/18. Now we can subtract the fractions:
12 8/18 - 10 2/3 = 12 4/9 - 10 6/9 = 2 10/9 gallons
Therefore, there is 2 10/9 gallons of gas left in Susan's car's tank.
