the gas tank of a car is 2/3 full. a trip uses up 1/4 of the gas in the tank. how full is the tank at the end of the trip?
please include how you got the answer,
thanks

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
