2007,2007+2008,2008+2009,2009
=2007 x 1,0001+ 2008 x 1,0001 + 2009 x 1,0001
= 1,0001 x (2007+2008+2009)
=1,0001 x 6024

2007,2007 + 2008,2008 + 2009,2009
= ( 2007,2007 + 1,0001 ) + 2008,2008 + ( 2009,2009 - 1,0001 )
= 2008,2008 + 2008,2008 + 2008,2008
= 2008,2008 x 3

Trả lời :
\(132+77+198=12.11+11.7+11.18=11.\left(11+7+18\right)\)
\(=11.37\)\(=407\)
Study well!
\(132+77+198\)
\(=11\times12+11\times7+11\times18\)
\(=11\times\left(12+7+18\right)\)
\(=11\times37\)
\(=407\)

a, 132 + 77 + 198 = 12.11 + 7.11 + 18.11 = 11.( 12 + 7 + 18 ) = 11.37
b, 5555 + 6767 + 7878 = 55.101 + 67.101 + 78.101 = 101.( 55 + 67 + 78 ) = 101.200
a) 132 +77+198
= 11 x 12+11 x 7 + 11 x 18
= 11 x ( 12 + 7 +18 )
= 11 x 37
b) 5555 + 6767 +7878
= 101 x 55 + 101 x 67 + 101 x 78
= 101 x ( 55 + 67 + 78 )
= 101 x 200

k cho mik nha
bài 1 : 26,75 + (8232 : 84 - 68,5) x 11
=26,75 + 29,5 x 11
= 26,75 + 324,5
= 351,25
bài 2 : 2007 x 1,0001 + 2008 x 1,0001 + 2009 x 1,0001
= (2007 + 2008 + 2009 ) x 1,0001
= 6024 x 1,0001
