Ta có :
\(\frac{35}{15}=\frac{7}{3}\)
\(\frac{7}{3}+\frac{7}{10}=\frac{70}{30}+\frac{21}{30}\)
\(=\frac{70+21}{30}\)
\(=\frac{91}{30}\)
Vậy : \(\frac{35}{15}+\frac{7}{10}=\frac{91}{30}\)
bằng 91/30
đúng đó

\(\frac{35}{15}+\frac{7}{10}\)
= \(\frac{7}{3}+\frac{7}{10}\)
= \(\frac{70}{30}+\frac{21}{30}\)
= \(\frac{91}{30}\)
= \(3\frac{1}{30}\)
