Ai tl đúng và giải chi tiết thì mk tk cho

mk tk cho 3 tk nhé

(37.13-13)/(24+37.12)

=(36.13)/(24+37.12)

=(36.13)/(12.2+37.12)

=(36.13)/(39.12)

=(3.1)/(3.1)

=3/3=1

\(\frac{37.13-13}{24+37.12}\)

\(=\frac{37.12+37-13}{24+37.12}\)

\(=\frac{37.12+24}{24+37.12}\)

\(=1\)

= \(\frac{13\left(37-1\right)}{12\left(2+37\right)}=\frac{13.36}{12.39}=1\)

37.13+13

24+37.12

=13.(37-1)

đăng nhầm

\(\frac{37.13-13}{24+37.12}=\frac{13-13}{24+12}=\frac{1}{36}\)

Xét tử số:

=37.13 - 13.1 

= 13. (37-1) = 13.36

Xét mẫu số:

=12.2+37.12

=12.(37+2) = 12.39

\(\frac{13.36}{12.39}=\frac{13.12.3}{12.3.13}=1\)

(sau khi đã rút gọn)

xét tử số:

=37,13-13,1

=13x(37-1)

=13,36

xét mẫu số:

=12,2+37,12

=12x(37+2)

=12,39\(\frac{13,26}{12,39}=\frac{12.12.3}{12.3.13}=1\)

\(\frac{37.13-13}{24+37.12}\)=\(\frac{37.\left(12+1\right)-13}{24+37.12}\)=\(\frac{37.12+37-13}{24+37.12}\)=\(\frac{37.12+24}{24+37.12}\)=1

\(\frac{37.13-13}{24+37.12}\)

\(=\frac{37.12+37-13}{24+37.12}=\frac{37.12+24}{24+37.12}=1\)

#

(37.13-13)/(24+37.12)

= 1

#

Ta có \(37.13-13=37.\left(12+1\right)-13\)

\(=37.12+37-13\)

\(=37.12+24\)

Do đó \(\frac{37.13-13}{24+37.12}=\frac{37.12+24}{37.12+24}\)

nên số dư sẽ là 0

( 37.13 - 13 ) : ( 24 + 37.12 ) = [ 13 . ( 37 - 1 ) ] : ( 12.2 + 37.12 )

                                          = [ 13 . 36 ] : [ 12. ( 2 + 37 ) ]

                                          = [ 13.3.12 ] : [ 12 . 39 ]

                                          = [ 39 . 12 ] : [ 12 . 39 ]

                                          =  1.

\(\frac{37\times13-13}{24+37\times12}\)

\(=\frac{27\times12+37-13}{24+37\times12}\)

\(=\frac{24+37\times12}{24+37\times12}\)

\(=1\)
