The answer for the greatest common factor of 12 and 16 is 4
Answer:
1.→n=15
2.→n=0
Step-by-step explanation:
The two expressions given are
⇒A number is said to be rational if it can be expressed in the form of , where ,q≠0.And it's decimal expansion will be either terminating or non terminating repeating.
We have to find smallest value of n, for which each of these two expressions will be rational.
So, 1.→n=15
and 2.→n=0

Answer:
Kevin will take 3 hours to make all pieces.
Step-by-step explanation:
Kevin is building a large model of a soccer ball which is made of 20 hexagons and 12 pentagons.
Time taken by Kevin to measure and cut each hexagon = 6 minutes
Therefore, time taken to make 20 hexagons = 6×20 = 120 minutes
Similarly time taken by him to measure and cut a pentagon = 5 minutes
So, time taken to make 12 pentagons = 12×5 = 60 minutes
Total time taken to measure and cut 12 pentagons and 20 hexagons = 60+120 = 180 minutes
Therefore, Kevin will take 180 minutes or 3 hours to make all pieces.
