This was my answer for someone else question exactly like this :)
Answer:
First, you change each number to an improper fraction, simplify if possible. Then Multiply the numerators and then denominators, put your answer at lowest terms.
I really hope this helped.!

Second one 12x9=108
3rd one = 3x4=12
