Lynn put 3 7/8 gallons of gas in her gas tank. if there are now 18 1/6 gallons in the tank, how many gallons did she start with?? Please I need an answer ASAP worth 25 points

14.3 gallons      = 4 + 7.25/25  or 14.29 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.

1.0

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
