The ratio is people to buses so that is the order in which the ratio should be set up in People:Buses 150:6 (however you are not done, this can be simplified) Try by dividing 6 from either sides. In that case you will get 25:1
BTW, don't be fooled by the other options
The answer to F is wrong because although ration is simplied, its in the wrong order The answer H is wrong because its in the wrong order and is not simplified Though the answer to I seems right because of the order, its not simplified and lacks the : symbol
