\(\frac{39}{75}=\frac{39:3}{75:3}=\frac{13}{25}\)
\(\frac{48}{78}=\frac{48:6}{78:6}=\frac{8}{13}\)
\(\frac{120}{90}=\frac{120:30}{90:30}=\frac{4}{3}\)
_HT_
\(\dfrac{48}{78}=\dfrac{48:6}{78:6}=\dfrac{8}{13}\)
\(\dfrac{39}{75}=\dfrac{39:3}{75:3}=\dfrac{13}{25}\)
\(\dfrac{120}{90}=\dfrac{120:30}{90:30}=\dfrac{4}{3}\)
\(a,\dfrac{225}{900}=\dfrac{225:225}{900:225}=\dfrac{1}{4};b,\dfrac{125125}{250250}=\dfrac{125125:125125}{250250:125125}=\dfrac{1}{2}\)
\(a) \frac{1}{4};\frac{3}{7};\frac{101}{131}\)
\(15\div\frac{15}{45}\div15=\frac{1}{3}\)
\(\frac{72}{90}=72\div\frac{18}{90}\div18=\frac{4}{5}\)
\(50\div\frac{10}{120}\div10=\frac{5}{12}\)
1000000000000% đúng nha
\(a,\frac{24}{56}=\frac{24:8}{56:8}=\frac{3}{7}\)
\(b,\frac{120}{90}=\frac{120:30}{90:30}=\frac{4}{3}\)
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!
\(\dfrac{120}{90}=\dfrac{4}{3}\)
\(\dfrac{39}{75}=\dfrac{13}{25}\)
\(\dfrac{225}{900}=\dfrac{1}{4}\)
120/90=4/3
39/75=13/25
225/900=1/4
