You first need to make the denominators on both fractions the same and how to do that is simple. What does 6 and 8 go into to? Well, the answer is 24. You multiply 5/6 into 4 and you should get 20/24. Then, you multiply 3/8 into 3 and you should get 9/24. Now the last part is easy, you just subtract 20/24 and 9/24 and you should get 11/24 as your answer. It cannot be simplified. Hope it helped.
Multiply 209 by 12 to find one year which is 2508 Multiply 2508 by 4 to find 4 years which is 10032 Subtract 8500 from 10032 which is 1532 So he paid 1532 more than the cars original price I hope thats understandable!
