Question

So sánh phân số

\(\dfrac{5}{6}\) và \(\dfrac{7}{8}\)     

Cộng Phân Số

\(\dfrac{9}{4}+\dfrac{3}{5}\)

 

Answer 1

So sánh:

\(\frac{5}{6}=\frac{5\times4}{6\times4}=\frac{20}{24}\)

\(\frac{7}{8}=\frac{7\times3}{8\times3}=\frac{21}{24}\)

Mà \(\frac{20}{24}< \frac{21}{24}\) nên \(\frac{5}{6}< \frac{7}{8}\)

Cộng phân số:

\(\frac{9}{4}+\frac{3}{5}\)

\(=\frac{45}{20}+\frac{12}{20}\)

\(=\frac{57}{20}\)

Answer 2

TL:

\(\dfrac{5}{6}< \dfrac{7}{8}\) 

\(\dfrac{9}{4}+\dfrac{3}{5}\) = \(\dfrac{57}{20}\)
