1000000000000% đúng nha
\(\dfrac{120}{90}=\dfrac{4}{3}\)
\(\dfrac{39}{75}=\dfrac{13}{25}\)
\(\dfrac{225}{900}=\dfrac{1}{4}\)
a) 15 / 18 = 5/6 ( rút gọn cho 3)
b) 30/120 = 1/4 (rút gọn cho 30)
c) 45 / 27 = 5/3 ( rút gọn cho 9 )
d) 75 / 300 = 1/4 (rút gọn cho 75)
a)là \(\frac{5}{6}\) b)là \(\frac{1}{4}\) c)là \(\frac{5}{3}\) d)là \(\frac{1}{4}\)
tik nha bạn thân!

ukm ko có j
\(\frac{39}{75}=\frac{39:3}{75:3}=\frac{13}{25}\)
\(\frac{48}{78}=\frac{48:6}{78:6}=\frac{8}{13}\)
