B) 15 1/4 gallons
C) 1 7/10 gallons
D) 1 2/5 gallons

Answer 1

Maria had 1 3/5 gallons of gas in her tank before she filled up. So, the correct answer is A) 1 3/5 gallons.

Step-by-step explanation:

To find the number of gallons of gas that were in Maria's tank before she filled up, we can subtract the amount of gas she put in her car (13 3/5 gallons) from the total capacity of her gas tank (15 1/4 gallons). Here's how:

Convert both mixed numbers to improper fractions: 13 3/5 = 68/5 and 15 1/4 = 61/4.

Find the difference between the two fractions: (61/4) - (68/5).

Convert the result back to a mixed number: 1 3/5 gallons.

Thus, the correct answer is A) 1 3/5 gallons.
