Jesse purchased a full tank of gas on Thursday on Friday he took a road trip and use one half of a tank on Sunday he did the same here and use an additional one third of the tank how much gas does Jesse have left

Thursday: got full tank of gas

friday: took a road trip, used one half the tank. One half of a tank of gas left

sunday: did the same here and used an additional one third of the tank

1/2 tank of gas minus 1/3 tank of gas = how much he has left

first you need a common denominator, we're going to use 6

then you need to multiply each fraction by 1 to get it to the same denominator.

to get the denominator of 2 to 6, you multiply by 3 so

1 x 3 = 3

2 3 6

do the same for 1/3, except multiply by 2 on both sides

1 x 2 = 2

3 2 6

now just subtract the two fractions

3 - 2 = 1

6 6 6

Jesse has 1/6 tank of gas left.
