( 37 . 13 - 13 ) : ( 24 + 37 . 12 )

=  ( 481 - 13 ) : ( 24 + 444 )

= 468 : 468

= 1

\(\left(37.13-13\right):\left(24+37.12\right)\)

 \(=468:468\)

  \(=1\)

\(\left(37.13-13\right):\left(24+37.12\right)\)

\(=468:468\)

 \(=1\)

\(A=\frac{37\cdot13-13}{24+37\cdot12}=\frac{37\cdot\left(12+1\right)-13}{24+37\cdot12}=\frac{37\cdot12+37-13}{24+37\cdot12}=\frac{37\cdot12+24}{24+37\cdot12}=1\)

BẠN VÔ fx mà ghi

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

câu này giống bài của mình,cầu mong các bạn giúp đỡ   ^-^

a, 4

b, 100

c, / ko biết là cái j nên ko giải đc

a, 1990 . 1990 - 1992 . 1988

=  3960100      - 3960096

= 4 .

b, ( 1374 . 57 + 687 . 86 ) : ( 26 . 13 + 74 . 14 )

=  ( 78318      + 59082    ) : ( 338       + 1036    )

=          137400                   :      1374

=                              100 .

c, \(\frac{37.13-13}{24 +37.12}\)

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

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

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

\(=1\)

37.13+13

24+37.12

=13.(37-1)

đăng nhầm

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

\(\frac{13.\left(37-1\right)}{12\left(2+37\right)}=\frac{13.36}{12.39}=\frac{13.4.3.3}{4.3.3.13}=1\)

học tốt nhé

ủng hộ nhé

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

\(\frac{37.13-13}{24+37.12}\)= \(\frac{37.12+37-13}{24+37.12}\)= \(\frac{37.12+24}{24+37.12}\) = 1

\(\frac{37.13-13}{24+37.12.\left(x-2\right):5}=16\)

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

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

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

\(=1\)

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