\(\frac{8}{12};\frac{12}{15};\frac{15}{20}\)
MSC : 60
\(\frac{8}{12}=\frac{8\times5}{12\times5}=\frac{40}{60}\)
\(\frac{12}{15}=\frac{12\times4}{15\times4}=\frac{48}{60}\)
\(\frac{15}{20}=\frac{15\times3}{20\times3}=\frac{45}{60}\)
Vậy quy đồng mẫu số 3 phân số \(\frac{8}{12};\frac{12}{15};\frac{15}{20}\) ta được \(\frac{40}{60};\frac{48}{60};\frac{45}{60}\)
\(MSC:60\)
\(\frac{8}{12}=\frac{40}{60}\)
\(\frac{12}{15}=\frac{48}{60}\)
\(\frac{15}{20}=\frac{45}{60}\)

TL:
8/12 = 40/60 ; 12/15 = 48/60 ; 15/20 = 45/60
Nhớ k mình nha
HT
ta có mẫu số chung là 60
8/12=40/60
12/15=48/60
15/20=45/60
Tíc cho mk nhé
HT
\(\frac{8}{12}=\frac{8.5}{12.5}=\frac{40}{60}\)
\(\frac{12}{15}=\frac{12.4}{15.4}=\frac{48}{60}\)
\(\frac{15}{20}=\frac{15.3}{20.3}=\frac{45}{60}\)
HT
\(\frac{8}{12},\frac{12}{15},\frac{15}{20}\)MSC 60
\(\frac{8}{12}=\frac{8\times5}{12\times5}=\frac{40}{60}\)
\(\frac{12}{15}=\frac{12\times4}{15\times4}=\frac{48}{60}\)
\(\frac{15}{20}=\frac{15\times3}{20\times3}=\frac{45}{60}\)
HT nhé
8/12=40/60
12/15=48/60
15/20=45/60
hok tốt nha
ok nhaaaaa
đúng thì nhớ k nha
