 (124.237 +152) : ( 870+235.122 )

=( 29388  +152) :  (870+  28670  )

=          29540    :      29540

=                       1

   ( 124.237 + 152 ) : ( 870 + 235.122 )

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

= 29540 : 29540

= 1

Answer : 1

(124.237+152):(870+235.122)

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

=29540:29540

=1

\(\frac{124.237+152}{235.122+870}=\frac{122.247+2.237+152}{237.122-2.122+870}=\frac{122.237+474+152}{237.122-244+870}=\frac{122.237+626}{237.122+626}=1\)

(124.237+152):(870+235.122)

= 29540 : 29540

= 1

(124.237+152):(870+235.122)

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

= 29540 : 29540 

= 1

= 29540 : 29540

= 1

a) 1990.1990 - 1992.1988

= 1990.1990 - (1990 + 2)(1990 - 2)

= 1990.1990 - 1990.1990 + 4 = 4

b) (1374.57 + 687.86) : (870 + 235.122)

= (1374.57 + 687.2.43) : (10.87 + 5.47.2.61)

= (1374.57 + 1374.43) : (10.87 + 10.47.61)

= [1374(57 + 43)] : [10(87 + 47.61)]

= (1374.100) : [10(87 + 47.61)] (đoạn này mẫu số xấu quá, hetcuu)

c) (124.237 + 152) : (870 + 235.122)

= (124.235 + 124.2 + 152) : (870 + 235.122)

= (122.235 + 2.235 + 2.124 + 152) : (870 + 235.122)

= (122.235 + 470 + 248 + 152) : (235.122 + 870)

= (122.235 + 870) : (235.122 + 870) = 1

d) \(\dfrac{423134\cdot846267-423133}{846267\cdot423133+423134}=\dfrac{423133\cdot846267+846267-423133}{846267\cdot423133+423134}\)

\(=\dfrac{423133\cdot846267+423134}{846267\cdot423133+423134}=1\)
