Answer 1

108    12                                                             108     12

342    x                                                                702      x

108x =342*12                                                    108x=702*12  

x=38                                                                    x= 78

108     12                                                            108     12

x          15                                                             x       42

12x=108*15                                                        12x=108*42

x=135                                                                   x=378
