\(\dfrac{24}{1000}=\dfrac{24:8}{1000:8}=\dfrac{3}{125}\)

Ta có:

\(\begin{array}{l}\frac{{24}}{{108}} = \frac{{24:12}}{{108:12}} = \frac{2}{9};\\\frac{{80}}{{32}} = \frac{{80:16}}{{32:16}} = \frac{5}{2}\end{array}\)

 Ta có: \(\frac{{12}}{{ - 24}} = \frac{{12:12}}{{ - 24:12}} = \frac{1}{{ - 2}}\)

\(\frac{{ - 39}}{{75}} = \frac{{ - 39:3}}{{75:3}} = \frac{{ - 13}}{{25}}\)

\(\frac{{132}}{{ - 264}} = \frac{{132:132}}{{ - 264:132}} = \frac{1}{{ - 2}}\).

\(8m9dm=8m+\frac{9}{10}m=8\frac{9}{10}m\)

\(6m55cm=6m+\frac{55}{100}m=6\frac{55}{100}m\)

\(5dam4dm=5dam+\frac{5}{100}dam=5\frac{5}{100}\)

9 tấn 5 kg = 9 tấn + \(\frac{5}{1000}\)tấn =\(9\frac{5}{1000}\)tấn

\(\frac{21}{39}=\frac{21:3}{39:3}=\frac{7}{13}\)

\(\frac{16}{24}=\frac{16:8}{24:8}=\frac{2}{3}\)

\(\frac{36}{72}=\frac{36:36}{72:36}=\frac{1}{2}\)

Chúc bạn học tốt

\(\frac{1946\times131+1600}{132\times1946-346}\)

\(=\frac{1946\times131+1600}{131\times1946+1946-346}\)

\(=\frac{1946\times131+1600}{131\times1946+1600}=1\)

 0,9913769643

1946x131+1000/132x1946-346

=1946x131+1600/131x1946-1940-346

=1946x131+1600/131x1946+1600

=1

\(\frac{1946x131+1000}{132x1946-946}=\frac{1946x131+1000}{\left(131+1\right)x1946-946}=\frac{1946x131+1000}{131x1946+1946-946}=\frac{1946x131+1000}{1946x131+1000}=1\)

132x1946 phải trừ đi 946 mới đúng đề bạn nhé

= \(\frac{255926}{256526}=0,9976610558\)

\(\frac{24-12.13}{12+4.9}=\frac{24-156}{12+36}=\frac{-132}{48}=\frac{-11}{4}\)

\(\frac{24-12\cdot13}{12+4\cdot9}=\frac{24-156}{12+36}=\frac{-132}{48}=\frac{-11}{4}\)

\(\frac{24-12.13}{12+4.9}\)

\(=\)\(\frac{12.2-12.13}{12.1+12.3}\)

\(=\frac{12\left(2-13\right)}{12\left(1+3\right)}\)

\(=\frac{2-13}{1+3}\)

\(=\frac{-11}{4}\)

Rút gọn phân số: 

\(\frac{24-12.13}{12+4.9}=\frac{24-4.3.13}{12+4.9}=\frac{24-3.13}{12+9}=\frac{24-3.13}{12+3.3}=\frac{24-13}{12+3}=\frac{11}{14}\)

Sai thì thôi nhé!

\(\frac{24-12.13}{12+4.9}\)=\(\frac{24-156}{12+36}\)=\(\frac{-132}{48}\)=-\(\frac{11}{4}\)

Mình nhầm, đoạn cuối \(=\frac{11}{15}\), bạn sửa lại cho mình nhé!

Have a nice day!
