\(\frac{2}{5}+\frac{5}{12}=\frac{49}{60}\)
Tk nha
\(\frac{2}{5}+\frac{5}{12}=\frac{24}{60}+\frac{25}{60}=\frac{49}{60}\)
\(\frac{2}{5}+\frac{5}{12}=\frac{49}{60}\)
\(\frac{2}{5}+\frac{5}{12}=\frac{24}{60}+\frac{25}{60}=\frac{49}{60}\)
Ủng hộ !
\(\frac{2}{5}\)+ \(\frac{5}{12}\)= \(\frac{2x12}{5x12}\)và \(\frac{5x5}{12x5}\)= \(\frac{24}{60}\)+ \(\frac{25}{60}\)= \(\frac{49}{60}\)
tk mk nha bạn
