In order to find out what fraction of the tank had been empty we need to find out how many gallons were empty and then divide it by the maximum capacity of the tank.
Since he pumped 8 gallons of gas and it got full, that means that 8 gallons out of 12 gallon tank was empty.
Mathematically: 8/12 of the tank.
The biggest common factor of 8 and 12 is 4.
Divide the numerator and denominator with 4.
8/4=2
12/4=3
So 8/12=⅔
