To multiply fractions you can times the top and bottom numbers together, to get the answer: (12*3)/(1*4) = 36/4
Then you find a common number, a number you can divide the top and bottom fraction by to get a interger (whole number), in this case it is 4. Then you divide both the numerator and denominator by 4: (36/4)/(4/4) = 9/1
If a fraction has 1 as the bottom number, you can just write out the top number so: 9/1 = 9
