0,92 x 324 + 0,92 x 676

= 0,92 x ( 324 + 676)

= 9,92 x 1000

= 920

0,92 x 324 + 0,92 x 676

= 0,92 x ( 324 + 676)

= 0,92 x 1000

= 920

= ( 3233 + 6767) + ( 902 + 1098 )

= 10000 + 2000

= 12000

\(\text{= ( 3233 + 6767) + ( 902 + 1098 ) = 10000 + 2000 = 12000}\)

3233 + 6767 + 902 + 1098 

= ` ( 3233 + 6767 ) + ( 902 + 1098 ) `

= `10000 + 2000 `

= ` 12000 `

= 12,5x8,04 x2,5

=100,5 x2,5

=252,25

k mk nhé, chỗ nào sai nhắn mk nha

17.5 * 4 * 3 * 25

=(4*25)*17,5*3

=100*17,5*3

=1750.3

=5250

    17,5 x 4 x 3 x 25

= ( 4 x 25 ) x 17,5 x 3

=  100 x 17,5 x 3

=  1750 x 3 

=  5250

17,5x4x3x25=(25x4)x17,5x3=(100x17,5)x3=1750x3=5250

Đúng nha bạn!!!@~@

có sai đề k?

Chắc sai rồi

`7/9+9/7+6/9+11/7`

`=(7/9+6/9)+(9/7+11/7)`

`=13/9+20/7`

rồi thuận tiện  nào cái bài này=)

= ( 7/9 + 6/9 ) + ( 9/7 + 11/7 ) 

= 13/9 + 20/7

= 271/63

6/7 * 5/8*7/3*7/6*8/5

= 6*5*7*7*8 /7*8*3*6*5

=1*1*7*1*1/1*1*3*1*1

= 7/3 

1) \(=\left(\frac{3}{5}+\frac{2}{5}\right).\frac{6}{11}\)

\(=1.\frac{6}{11}\)

\(=\frac{6}{11}\)

2)\(\frac{17}{25}.\left(\frac{11}{19}+\frac{6}{19}+\frac{2}{19}\right)\)

\(=\frac{17}{25}.1\)

\(=\frac{17}{25}\)

2.\(\frac{17}{25}.\frac{11}{19}+\frac{17}{25}.\frac{6}{19}+\frac{17}{25}.\frac{2}{19}=\frac{17}{25}\left(\frac{11}{19}+\frac{6}{19}+\frac{2}{19}\right)\\ =\frac{17}{25}.1\\ =\frac{17}{25}\)
