27 and 36 have a Greatest Common Factor of 9 so...
27/36 = 3/4
Step-by-step explanation:
I'm not sure if I got the correct answer since English is not my first language
1 yard = 36 inches
so 720 inches = 720/36 = 20 yards.
The outlier is (10,9), because it's not only point thats away from the other ones.
78 is the answer BEST OF LUCK
