peachpi · Answer

the first thing you have to do is put the measurements in the same unit. How many inches is 9 feet?

togundeji · Answer

There would be a total of 108 inches in nine feet. @peachpi

peachpi · Answer

ratio of car length to model length means
$$\frac{ car~~length }{ model~~length }=\frac{ 108 }{ 10 }$$
reduce to lowest terms

togundeji · Answer

10.8? I divide 108 with 10. @peachpi

peachpi · Answer

well, you don't really want to divide, only reduce the fraction.
108 and 10 are both even, so you could divide them both by 2

togundeji · Answer

I divide 108 with 2 = 54
I divide 2 with 10 = 5 

So would the answers be A?
