Answer 4

\(\text{( 124 x 237 + 152 ) : ( 870 + 235 x 122 )}\)

\(\text{= ( 29388 + 152 ) : ( 870 + 28670 )}\)

\(\text{= 29540 : 29540 }\)

\(\text{= 1}\)

Answer 5

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