1)  

 What number should be multiply 62 to get 128

Answer: 12


SOLUTION 1 :

Soln  :

The product of two rational numbers  =   128

Given number x Required number    =   128

    62 x Required number          =   128

                     Required number         = 128 x 26

                                                              = 12



2)  

 What number should be multiply 93 to get 108

Answer: 512


SOLUTION 1 :

Soln  :

The product of two rational numbers  =   108

Given number x Required number    =   108

    93 x Required number          =   108

                     Required number         = 108 x 39

                                                              = 512



3)  

 What number should be multiply 114 to get 194

Answer: 1911


SOLUTION 1 :

Soln  :

The product of two rational numbers  =   194

Given number x Required number    =   194

    114 x Required number          =   194

                     Required number         = 194 x 411

                                                              = 1911



4)  

 What number should be multiply 104 to get 112

Answer: 115


SOLUTION 1 :

Soln  :

The product of two rational numbers  =   112

Given number x Required number    =   112

    104 x Required number          =   112

                     Required number         = 112 x 410

                                                              = 115



5)  

 What number should be multiply 73 to get 147

Answer: 67


SOLUTION 1 :

Soln  :

The product of two rational numbers  =   147

Given number x Required number    =   147

    73 x Required number          =   147

                     Required number         = 147 x 37

                                                              = 67



6)
