The tank for a car holds 15 gallons. The gasoline gauge shows the tank is \( \frac{2}{3} \) full. How much gas is still in the tank? Give your answer as a whole number or as a mixed fraction reduced to lowest terms.

The tank holds 15 gallons, and if it's \( \frac{2}{3} \) full, you can find the amount of gas by multiplying the total capacity by the fraction. So, \( \frac{2}{3} \times 15 = 10 \) gallons. Therefore, there are 10 gallons of gas still in the tank! And that’s the perfect amount for a quick road trip! To put it into perspective, with 10 gallons, you could cruise for miles depending on your car's fuel efficiency. Just make sure to always keep an eye on that gauge, so you’re not caught in a sticky situation with an empty tank!
