1933/120 nha bạn

= ( 3/4+25/100)+(7/12+5/12)+(21/37+16/37)

= (3/4+1/4)+(7/12+5/12)+(21/37+16/37)

= 1+1+1

= 3

(3/4+1/4)+(7/12+5/12)+(21/37+16/37)

=1+1+1

=3

= 3 nha bn

chúc bn học tốt!!!!!!!!!!!!!!!!!!!!!

A)    (12 x 2 + 12 x 4 + 12 x 6) : ( 2 + 4 + 6 + ... + 12 + 14)
     = [12 x ( 2 + 4 - 6 )] : ( 2 + 4 + 6 + ... + 12 + 14)
     = [12 x 0 ] : ( 2 + 4 + 6 + ... + 12 + 14)
     = 0 : ( 2 + 4 + 6 + ... + 12 + 14)
     = 0 
B)    37 x 49 + 37 x 2 x 25 + 37 
     = 37 x (49 + 2 x 25 + 1)
     = 37 x 100 
     = 3700

Học dỏi nha :)))
~ Good luck ~

Sai cái dì mà mí người k sai nhiều quá v ?? :D ?? 

Sai cái dề :D ???????

(4 x 25 x 8) +( 4 x 37 x 8) + (2 x 36 x 16)

= 3136

hok tốt !

(4 x 25 x 8) +( 4 x 37 x 8) + (2 x 36 x 16)

= 3136

nhanh mà

\(3\cdot25\cdot8+4\cdot37\cdot6+2\cdot38\cdot12\)

\(=24\cdot25+24\cdot37+24\cdot38\)

\(=24\left(25+37+38\right)=24\cdot100=2400\)

Tính nhanh 

3 . 25 . 8 + 4 . 37 . 6 + 2 . 38 . 12=2400

3.25.8+4.37.6+2.38.12

=24.25+24.37+24.38

=24(25+37+38)

=24.100

=2400
