The fraction 8/21 cannot be simplified because the numerator and denominator don't have a common factor except 1.
Answer:
6/8 and 9/12
Step-by-step explanation:
You can find any by multiplying numerator and denominator by any given number. The number multiplied has to be the same for the top and the bottom

2. Number is 3
3/4*3/3 = 9/12 (3*3 = 9 and 3*4 = 12)
