\(\frac{3}{4}+\frac{5}{12}=\frac{9}{12}+\frac{5}{12}=\frac{9+5}{12}=\frac{14}{12}=\frac{7}{6}\)
chúc bn học giỏi!
thánks
bn học lớp mấy?
\(\frac{3}{4}+\frac{5}{12}=\frac{3\cdot3}{4\cdot3}+\frac{5}{12}=\frac{9}{12}+\frac{5}{12}=\frac{14}{12}=\frac{7}{6}\)
\(\frac{3}{4}+\frac{5}{12}=\frac{3\times3}{4\times3}+\frac{5}{12}=\frac{9}{12}+\frac{5}{12}=\frac{14}{12}\)
\(\frac{3}{4}+\frac{5}{12}\)
= \(\frac{9}{12}+\frac{5}{12}\)
= \(\frac{14}{12}\)
\(\frac{3}{4}+\frac{5}{12}=\frac{9}{12}+\frac{5}{12}=\frac{14}{12}=\frac{7}{6}\)
