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

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

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

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

\(=1\)

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

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

37.13+13

24+37.12

=13.(37-1)

đăng nhầm

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

(37.13-13)/(24+31.12)
=(13.(37-1))/(12.(2+31))
=13.36/12.33
=13.3/33
=13/11

=\(\frac{13}{11}\)

=\(\frac{13}{11}\)

( 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.

C  = \(\frac{101+100+99+98+...+3+2+1}{101-100+99-98+...+3-2+1}\)

\(C=\frac{\left(101+1\right).101:2}{1+1+...+1+1}\)

\(C=\frac{5151}{51}\)

\(C=101\)

b) \(D=\frac{3737.43-4343.37}{2+4+6+...+100}\)

\(D=\frac{37.101.43-43.101.37}{2+4+6+...+100}\)

\(D=\frac{0}{2+4+6+...+100}\)

\(D=0\)

a)C=101

b)d=0

a) \(C=\frac{101+100+99+98+...+3+2+1}{101-100+99-98...+3-2+1}\)

\(=\frac{\left(101+1\right).\left[\left(101-1\right):1+1\right]:2}{\left(101-100\right)+\left(99-98\right)+\left(3-2\right)+1}\)

\(=\frac{102.101:2}{1+1+...+1}\)

\(=\frac{51.101}{51}\)

\(=101.\)
