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

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

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

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

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

Bài 1:

\(\frac{37.13-13}{24+37.12}=\frac{13.\left(37-1\right)}{2.12+37.12}=\frac{13.36}{12.\left(37+2\right)}=\frac{13.36}{12.39}=\frac{1.3}{1.3}=1\)

Bài 2:

\(\frac{101+100+...+2+1}{101-100+99-98+...+3-2+1}=\frac{\left[\left(101-1\right):1+1\right].\left(101+1\right):2}{\left(101-100\right)+\left(99-98\right)+...+\left(3-2\right)+1}\)\(=\frac{101.102:2}{1.\left[\left(101-1\right):2+1\right]}=\frac{5151}{1.51}=\frac{5151}{51}=101\)

\(\frac{3737.43-4343.37}{2+4+...+100}=\frac{37.101.43-43.101.37}{2+4+...+100}=\frac{0}{2+4+6+...+100}=0\)

37.13-13  =13-13= 1

24+37.12  24+12  36
