Help me solve this!!
Joeys father stops at the gas station to buy gas. The car has a 16 gallon tank, and the feul gauge says there are 3-4 of a tank of gas. If joeys dad buys 6 gallons of gas, what fraction of the tank will the car´s feul gauge read??
thanks,

To solve this problem, we need to determine the fraction of the tank that the car's fuel gauge will read after Joey's dad buys 6 gallons of gas.
First, let's determine the amount of gas in the tank before Joey's dad buys any gas. The fuel gauge indicates that there are 3-4 of a tank of gas, which means that there are 3/4 * 16 = 12 gallons of gas in the tank.
Next, let's calculate the amount of gas in the tank after Joey's dad buys 6 gallons of gas. We add the 6 gallons to the initial amount of gas, which gives us a total of 12 + 6 = 18 gallons of gas in the tank.
Finally, we need to calculate the fraction of the tank that the car's fuel gauge will read. Since the car has a 16-gallon tank, and there are now 18 gallons of gas in the tank, the fraction of the tank that the fuel gauge will read is 18/16.
We can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2 in this case. Simplifying gives us a fraction of 9/8.
Therefore, the car's fuel gauge will read 9/8 of a tank of gas after Joey's dad buys 6 gallons.
