well,,firstly you should convert both the lengths into same units..

shubhamsrg · Answer

1 feet = 12 inches..

anonymous · Answer

Well, it would take 2 models to form one foot. Therefore, doubled the size of the 9..

shubhamsrg · Answer

eh ?

shubhamsrg · Answer

9 feet= 9*12 inches
now find ratio.
take both measurements in inches..

anonymous · Answer

That would make 108 : 18 correct?

shubhamsrg · Answer

how do you get 18 in denominator ? o.O
though 108 seems correct..

anonymous · Answer

Oh wait I see. I thought we were going to convert the model's measurement into feet and go from there. So.. 108 : 6. Therefore, 108 divided by 6 = 18.

shubhamsrg · Answer

yep..bang on target!
so whats the final ans ?

anonymous · Answer

1 : 18 yes?

shubhamsrg · Answer

hmm..
nopes..try again..
and dont guess..

shubhamsrg · Answer

i mean dont guess,,arrive to the ans..
length of car should be in numerator .

anonymous · Answer

Okay, so by dividing 6 by 108 we get 18. This means that we found the length of the car, correct? Therefore, it would be 18 : 1. However, if this is the case, then what makes the denominator 1?
