I will show you the answer and the EXAMPLE for number one, ok?
#1: 6 8/9 x 12 1/2
6x12=72
8x1=8
9x2=18
so, 72 (If you simplify the 72, you will get 36)  8/18
simplify.
divide by 2
36 9/4
I can do the others.
6x2=12 
15x2=30
9x14=126
you just find their mixed numbers and multiply numerator by the numerator and the denominator to the denominator.
6 8/9 x 12 1/2
^ ^
62/9 x 25/2= 1550/18= 775/9=86 1/9
