It would be 57 suvs and 38 sedans sold to be a rational of 3:2
-2 / 1/4
If you are dividing you have to switch 1/4 to 4/1
-2/1 / 4/1
= -8
Hope this helped
Use KMF (Keep multiply flip)
keep the first fraction as it is
change sign to multiplication
flip numerator and denominator of last fraction
then finish
