Hi . im trying to find a ratio in the form of a: b: c . it's number of cars sold, a is 19 b is 57 c is 38. i need to find the ratio in its simplest form? and show how i got the answer.

  " 1:3:2 " .

Step-by-step explanation:

a:b:c :: 19:57:38 ;

Note that "a, b, and c" are all multiples of "19" ;  and as such; can all be evenly divided by "19".

19/19 = 1 ;

57/19 = 3 ;

38/19 = 2 .

So;  a:b:c::19:57:38::1:3:2 .

The answer is:  " 1:3:2 " .

Hope this helps!

   Best wishes to you!
