yes it is possible to get a common denominator grater than 12 and still get the right answer.
Step-by-step explanation:
This is because the numerator is always directly corelated to de denominator therefore the fraction wouldn't change because when simplified it is the same fraction as it would be with 12 as the denominator
Divide 35423 by 15 and round the answer down to a whole number, then you get 2361. If you subtract 15*2361 from 35423 you get the remainder 8. So answer C is correct.
