If the car can travel 81 km in one hour, (60 minutes) that means that it can travel 81/60 in a minute. The result is 1.35, and this times 15 will give you the amount the car can travel in 15 minutes. The answer is 20.25km. Then you would divide 20.25 and 15 to get your answer.

This is how I find the GCF.

I find the prime factors. 

63/3 = 21
21/3 = 7
7/7 = 1 

81/3 = 27
27/3 = 9
9/3 = 3
3/3 = 1

Then I find the common prime factors:
63: 3 x 3 x 7
81: 3 x 3 x 3 x 3 

Then I multiply the common prime factors:
3 x 3 = 9

The GCF for 63 and 81 (number 3) is 9. 

I bet you can use this method for all the other GCFs! :)

For this one, find the prime factors like before, and if there aren't any besides one, then it's a prime number. 

75/3 = 25
25/5 = 5
5/5 = 1
 
The prime factorization for 75 is 3 x 5 x 5

(I don't know the answer to 7, 8, 9, 10, 11, 12, 25, or 26, sorry!)
