Question

The gas tank of bus A was 2/3 full of gas. A trip used 2/3 of that gas in the tank. What fraction of gas was used up? The gas tank of bus B was 2/6 full of gas. A trip used 3/4 of that gas in the tank. What fraction of gas was used up? Who used up more gas and by how much more?

Answer 1

Answer:For Bus A:

- The fraction of gas used for the trip is: (2/3) x (2/3) = 4/9

- This means that 4/9 of the gas in the tank was used up.

For Bus B:

- The fraction of gas used for the trip is: (2/6) x (3/4) = 1/4

- This means that 1/4 of the gas in the tank was used up.

Therefore, Bus A used up more gas than Bus B by (4/9 - 1/4) = 1/36.
