Question: When is Cheryl's birthday? Image via Facebook/Kenneth Kong All you have to do is subtract $1.00 from $1.10 and then divide that answer, $0.10 by 2, to get your final answer, $0.05. Think back to that problem about the dogs at the dog show and use the same logic to solve this problem. If you already know how the area of a parallelogram and the area of a triangle are related, then adding 79 and 10 and subsequently subtracting 72 and 8 to get 9 should make sense-but if you're still confused, then check out this YouTube video for a more in-depth explanation. In order to solve this problem, you need to understand how the area of a parallelogram works. Supposedly, some of the smart students were able to solve this in less than one minute. This question was used in China to identify gifted 5th graders. Question: Find the area of the red triangle. Of course, it's not actually possible for half a dog to compete in a dog show, but for the sake of this math problem let's assume that it is. But you're not done yet! You then have to add 6.5 to 36 to get the number of small dogs competing, which is 42.5. In order to figure out how many small dogs are competing, you have to subtract 36 from 49 and then divide that answer, 13, by 2, to get 6.5 dogs, or the number of big dogs competing.
