To find the amount of energy used by cars, we need to subtract the energy used by buses and trains from the total energy used by the transportation industry.
The fraction of energy used by cars is 4/9.
The fraction of energy used by buses and trains is 1/6.
To subtract fractions, we need a common denominator. The least common multiple of 9 and 6 is 18.
4/9 can be rewritten as 8/18.
1/6 can be rewritten as 3/18.
Therefore, cars use 8/18 - 3/18 = 5/18 more energy than buses and trains.
The answer is 5/18.
Cars use about 4 over 9 of the energy consumed by the transportation industry. Buses and trains
use 1 over 6. How much more energy is used by cars than by buses and trains?
