chị Linh ko trả lời à, bùn zậy

\(\dfrac{72\times75}{125\times108}\) = \(\dfrac{36\times2\times25\times3}{25\times5\times36\times3}\) = \(\dfrac{2}{5}\)

\(\frac{-334}{320}=\frac{-334\div2}{320\div2}=\frac{-167}{160}\)

\(\frac{451}{200}=\frac{451}{200}\)

mình cần gấp .

=5/28

125/700= 5/28

\(\dfrac{15}{125}=\dfrac{3}{25}\)

\(\dfrac{15}{125}=\dfrac{15:5}{125:5}=\dfrac{3}{25}\)

a, =5/14

b, = 1/6

c, = 3/2

d, = 8/7

5/14

1/6

3/2

8/7

a,5/14

b,1/6

c,3/2

d,8/7

\(\frac{125}{2000}=\frac{125:125}{2000:125}=\frac{1}{16}\)

 rut gon bang : 

        1 phan  16

b: \(\dfrac{50}{125}=\dfrac{50:25}{125:25}=\dfrac{2}{5}\)

\(\dfrac{50}{125}=\dfrac{50:25}{125:25}=\dfrac{2}{5}\)

Ta có: \(\frac{{ - 18}}{{76}} = \frac{{ - 18:2}}{{76:2}} = \frac{{ - 9}}{{38}}\)

\(\frac{{125}}{{ - 375}} = \frac{{125:( - 125)}}{{ - 375:( - 125)}} = \frac{{ - 1}}{3}\)

\(-\dfrac{18}{76}=\dfrac{-9}{38};\dfrac{125}{-375}=-\dfrac{1}{3}\)
