( 124.237 + 152 ) : ( 870 + 235.122 )
=(29388+152)/(870+28670)
=29540/29540
=1
\(\left(124.237+152\right):\left(870+235.122\right)\)
\(=\left(29388+152\right):\left(870+235.122\right)\)
\(=29540:\left(870+28670\right)\)
\(=29540:29540\)
\(=1\)
ta có 124.237+152 =235.124+124.2+152
=235.124+400
=122.235+235.2+400=122.235+870:122.235+870=1

:\
( 124 x 237 + 152 ) : ( 870 + 253 x 122 )
= ( 29388 + 152 ) : ( 870 + 235 x 122 )
= 29540 : ( 870 + 28670 )
= 29540 : 29540
= 1
