2/3 x 1/4 = 2/12 = 1/6
Or make up a number for the size of th tank. Let's suppose it hols 21 (any unit you wish).
Then 2/3 x 21 = 14 when we start the trip.
If we use 1/4 of the 14 then 14 x 1/4 = 3.5 when the trip ends.
3.5/21 = 1/6

What if you have to do the math as 2/3-1/4?

Total is 2/3.
Trip uses 1/4 out of the total gas.....
It's not multiplication but subtraction.
Tank is 2/3 full. Trip uses 1/4 out of the 2/3 which means
2/3-1/4 = 5/12. So the tank is now 5/12 full after the trip used 1/4
