Answer 8

a)\(\dfrac{7}{9}và\dfrac{2}{3}\)  \(MSC:9\)

Giữ nguyên \(\dfrac{7}{9}\)

\(\dfrac{2}{3}=\dfrac{2.2}{3.2}=\dfrac{4}{9}\)

b)\(\dfrac{4}{10}và\dfrac{11}{20}\)  \(MSC:20\)

\(\dfrac{4}{10}=\dfrac{4.2}{10.2}=\dfrac{8}{20}\)

Giữ nguyên \(\dfrac{11}{20}\)

c)\(\dfrac{9}{25}và\dfrac{16}{75}\)  \(MSC:75\)

\(\dfrac{9}{25}=\dfrac{9.3}{25.3}=\dfrac{27}{75}\)

Giữ nguyên \(\dfrac{16}{75}\)
