Answer 1

 8 = x ==> 12x = 24 ==> x = 2
12   3
========================================================
 6 = 24 ==> 72x = 108 ==> x = 108
3x   36                                         72
================================================
4x = 3 ==> 20x = 24 ==> x = 24
8      5                                    20
