Cedric Buckley · Answer 1

First we find how much was left as 1/8 full

16.8 times 0.125

2.1

Now add this to the amount that was added to reach full gauge

2.1 + 16.8

18.9

Next we find out what 3/4 of a full tank is

18.9 times 0.75

14.175

So, the gas tank has 14.175 gallons when it is 3/4 full
