Answer 2

 ( 124 x 237 + 152 ) : ( 870 + 235 x 122) 
=[124 x (235+2) + 152 ] : [870 + 235 x (124-2)] 
=[124 x 235+124x2 + 152 ] : [870 + 235 x124 - 235x2] 
=[124 x 235+248 + 152 ] : [870 + 235 x 124 - 470] 
=[124 x 235+ 400 ] : [870 - 470 + 235 x 124 ] 
=[124 x 235+ 400 ] : [400 + 235 x 124 ] 
=1

Answer 3

( 124 x 237 + 152 ) : ( 870 + 235 x 122 )

= ( 29388 + 152 ) : ( 870 + 28670 )

= 29540 : 29540 

= 1

Answer 4

124x237+152= 122x237+626

870+235x122= 626+122x237

=> (124x237+152) : (870+235x122) =1

Answer 5

= (122*237+2*237+152) : (626+244+235*122)

= (122*237+474+152) : (626+2*122+235*122)

=(122*237+626):(626+237*122)

=1

Answer 6

( 124 x 237 + 152 ) : ( 870 + 235 x 122 )

= ( 29388 + 152 ) : ( 870 + 28670 )

= 29540 : 29540 

= 1

Answer 7

( 124 x 237 + 152 ) : ( 870 + 235 x 122 )

= ( 29388 + 152 ) : ( 870 + 28670 )

= 29540 : 29540 

= 1

Answer 8

\(\left(124.237+152\right):\left(870+235.122\right)\)

\(=29540:29540\)

\(=1\)
