Question

lyn put 3 7/8 gas in her gas tank. If there are now 18 1/6 gallons in her tank, how many gallons did she start with?

Answer 1

Answer:

14.3 gallons

Step-by-step explanation:

18 1/6 gallons - 3 7/8 = 14.29

18 - 3 = 15

1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667

You need to be careful here if you use basic subtraction, simply as two minus would change to addition.
