I set equations for all of them. 
x=the missing value

(#3) 96/15=8/x         Cross multiply
96x=120           Divide by 96 on both sides
x=1.25

(#4) 15/x=75/8         Cross multiply
75x=120           Divide both sides by 75
x=1.6

(#5) x/96=6/8           Cross multiply
8x=576           Divide both sides by 8
x=72

(#7) 3/42=8/x          Cross multiply
3x=336           Divide both sides by 3
x=112

(#8) x/12=9/84        Cross multiply
84x=108           Divide both sides by 84
x=1.29

(#9) 16/x=128/13          Cross multiply
128x=208             Divide both sides by 128
x=1.625
