Answer:
6 by 8
Explanation:
6 by 8 is a scaled replica because 3 times 2= 6 and 4 times 2=8. It is similar to doing ratios because you are multiplying both numbers by the same number, which is 2. You are just multiplying by the same number top and bottom. For example, when you convert fractions, you want to change your denominator. To do that you multiply the top and bottom numbers by how many you need to get your denominator. If you enlarge the top by two, you have to enlarge your bottom by 2 to make your scale replica equal.
