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
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

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