\(\frac{3600-75}{8400-175}=\frac{3525}{8225}=\frac{3525:1175}{8225:1175}=\frac{3}{7}\)

Chúc bạn may mắn!

38+1 =39

Tớ rút gọn thử nha!

    \(\frac{3600-75}{8400-175}\)

\(=\frac{3525}{8225}\)

\(=\frac{3525:25}{8225:25}\)

\(=\frac{141}{329}\)

\(=\frac{3}{7}\)

Tíck cho mìk vs nhoa hai hoang!

\(\frac{-72}{14}=\frac{-36}{7}\)

\(\frac{990}{2610}=\frac{11}{29}\)

\(\frac{374}{506}=\frac{17}{23}\)

\(\frac{3600-75}{8400-175}=\frac{3525}{8225}=\frac{3}{7}\)

hok tốt!!

\(\frac{3600-75}{8400-175}\)

\(=\frac{3525}{8225}\)

\(=\frac{3}{7}\)

\(\frac{71.52+53}{530.71-180}\)

\(=\frac{3745}{37450}\)

\(=\frac{1}{10}\)

1)

3600-75/8400-175

=48.75-75/48.175-175

=75.(48-1)/175.(48-1)

=75/175

=3/7

2)

Gọi tử là A 
Ta có A=530.71-180
A=53.71.10-180
A=(52.71+71).10-180
A=52.71.10+71.10-180
A=52.71.10+10.(71-18)
A=10.(52.71+53)
Ta có 71.52+53 / 530.71-180

= 71.52+53 / 10.(52.71+53)

=1/10

tích cho mình đi mình giai cho

\(\frac{3600-75}{8400-175}=\frac{75.48-75}{175.48-175}=\frac{75.\left(48-1\right)}{175.\left(48-1\right)}\)

\(=\frac{75}{175}=\frac{25.3}{25.7}=\frac{3}{7}\)

Trừ r dùng máy tính

Chỉ còn cách này nữa thôi

\(\frac{3600-75}{8400-175}=\frac{75.48-75}{175.48-175}\)

\(=\frac{75.\left(48-1\right)}{175.\left(48-1\right)}\)

\(=\frac{75}{175}=\frac{3}{7}\)

\(\frac{3600-75}{8400-175}=\frac{3525}{8225}\)

\(=\frac{3}{7}\)

Chúc bạn học tốt nha!
