\(\left(92,36\text{×}0,75+92,36\text{×}0,25\right)+\left(7,64:0,1:10\right)\)

\(=\left[92,36\text{×}\left(0,75+0,25\right)\right]+\left(7,64:0,1:10\right)\)

\(=\left(92,36\text{×}1\right)+7,64=92,36+7,64=100\)

\(\left[92,36\times\left(0,75+0,25\right)\right]+\left(76,4:10\right)\)

\(=\left(92,36\times1\right)+7,64\)

\(=10\)

sos sos sos !!!

Kkkkkkkkkkkkk kkkkkkkkkkkkk kkkkkkkkkkkkk kkkkkkkkkkkkk kkkkkkkkkkkkk 

TL:

=2,8×1,25+1,25×7,2=1,25×(2,8+7,2)=1,25×10=12,5

_HT_

    25,1 : 0,25 + 2,7 x 4 - 27,8 x 3,9

= 25,1 x 4 + 2,7 x 4 - 27,8 x 3,9

= 4 x ( 25,1 + 2,7) - 27,8 x 3,9

= 4 x 27,8 - 27,8 x 3,9

= 27,8 x ( 4 - 3,9)

= 27,8 x 0,1

= 2,78 

94.6 nhé:)

\(3,68:0,25+6\times3,68\\ =3,68\times4+6\times3,68\\ =3,68\times\left(4+6\right)\\ =3,68\times10\\ =36,8\)

\(=82\times\left(10,5+3,2\right)+13,7\times18\)

\(=13,7\times82+18\times13,7\)

\(=13,7\times\left(18+82\right)\)

\(=13,7\times100=1370\)

=

= 82 x (10,5 + 3,2) + 13,7 x 18
= 82 x 13,7 + 13,7 x 18
= 13,7 x (82 + 18)
= 13,7 x 100
=1370

7,7 x 0,25 - 0,1 + 2,4 x 0,25

= ( 7,7 + 2,4 ) x 0,25 - 0,1

= 10,1 x 0,25 - 0,1

= 2,525 - 0,1

= 2,425

Bạn chắc đúng không vậy?

\(7,7\times0,25-0,1+2,4\times0,25\)

\(=7,7\times0,25-0,4\times0,25+2,4\times0,25\)

\(=0,25\times\left(7,7-0,4+2,4\right)\)

\(=0,25\times9,7\)

\(=2,425\)

\(1,24:0,5+3,76.2\)

\(=2,48+7,52\)

\(=10\)

\(5,28:0,25+4,72.4\)

\(=21,12+18,88\)

\(=40\)

có ai giúp mik đi mai phải nộp rồi ​
