\(M=\frac{5555}{6666}-\frac{246246}{369369}+\frac{222222}{151515}=\frac{5}{6}-\frac{2}{3}+\frac{22}{15}=\frac{25}{30}-\frac{20}{30}+\frac{44}{30}=\frac{49}{30}\)
\(\frac{5555}{6666}\)= \(\frac{5}{6}\)
\(\frac{246246}{369369}\)= \(\frac{82}{123}\)
\(\frac{222222}{151515}\)= \(\frac{22}{15}\)
M= \(\frac{5}{6}\)+ \(\frac{82}{123}\)+ \(\frac{22}{15}\)
M= \(\frac{1025}{1230}\)+ \(\frac{820}{1230}\)+ \(\frac{6724}{1230}\)
M= \(\frac{1845}{1230}\)+ \(\frac{6724}{1230}\)
M= \(\frac{8569}{1230}\)
tk nhé
Mình giải thích nhé :\(\frac{5555}{6666}=\frac{5555:1111}{6666:1111}=\frac{5}{6};\frac{246246}{369369}=\frac{246246:123123}{369369:123123}=\frac{2}{3};\frac{222222}{151515}=\frac{222222:10101}{151515:10101}=\frac{22}{15}\)
Đoạn sau là quy đồng phân số rồi cộng lại thôi!
