Question 223869
Last year at a certain car dealership the ratio of cars to suv's sold was 5 to 3. If 400 cars were sold, how many SUV's were sold?


Step 1. Let x be the number of SUVs sold.


Step 2.  Form a ratio as follows:


{{{5/3=400/x=(Number-Of-Cars-Sold)/(SUVs-Sold)}}}


Step 3.  Multiply by 3x to get rid of denominators


{{{3x*(5/3)=3x*(400/x)}}}


{{{5x=1200}}}


Step 4.  Divide by 5 to both sides of the equation


{{{5x/5=1200/5}}}


{{{x=240}}}


Step 5.  ANSWER:  The number of SUVs sold was 240.


I hope the above steps were helpful.
