Question

Quy đông mẫu phân so 13/24 va 11/18

Answer 1

\(MSC:72\)

\(\frac{13}{24}=\frac{39}{72};\frac{11}{18}=\frac{44}{72}\)

vậy \(\frac{13}{24}< \frac{11}{18}\)( vì \(39< 44\))

Answer 2

Ta có \(\frac{13}{24}=\frac{13\times9}{24\times9}=\frac{117}{216}\)

            \(\frac{11}{18}=\frac{11\times12}{18\times12}=\frac{132}{216}\)
