This is the same as finding the prime factors of 210.

2 * 5 * 3 * 7 = 210

the answer is a because 6 times 2 eaquals 12 and you times thirty and twelve together and thats how you get 300 the easy way and how you could check if you are correct you could divide three hundred by 12 and you would get your answer. another way you could do it is dividing 300 by 30 ad getting 12 as your answer.
