Understanding Gas Tank Calculations

The video tutorial explains how to determine the amount of gas left in Tiffany's tank after a road trip. Initially, the tank is 7/8 full, and the tutorial walks through the process of calculating the remaining gallons using fractions and multiplication. The explanation includes simplifying the calculation by canceling out units and dividing by common factors, resulting in 14 gallons left in the tank.

What is the total capacity of Tiffany's gas tank?

• 12 gallons

• 14 gallons

• 16 gallons

• 18 gallons

What does it mean when the gas tank is 7/8 full?

• There are 7 gallons left in the tank.

• The tank is 7/8 of its total capacity full.

• There are 8 gallons left in the tank.

• The tank is almost empty.

Why is the information about the duration of the trip irrelevant?

• Because the car is fuel-efficient.

• Because Tiffany didn't drive far.

• Because the calculation only depends on the fraction of the tank that is full.

• Because the tank was already full.
