Ta có: \(\frac{a}{b}< \frac{c}{d}\) <=> \(ad< bc\)

<=> \(ad+ab< bc+ab\)

<=> \(a\left(b+d\right)< b\left(a+c\right)\)

<=> \(\frac{a}{b}< \frac{a+c}{b+d}\) (1)

Ta có: \(\frac{a}{b}< \frac{c}{d}\) <=> \(ad< bc\)

<=> \(ad+cd< bc+cd\)

<=> \(d\left(a+c\right)< c\left(b+d\right)\)

<=> \(\frac{a+c}{b+d}< \frac{c}{d}\) (2)

Từ (1) và (2) => \(\frac{a}{b}< \frac{a+c}{b+d}< \frac{c}{d}\left(dpcm\right)\)
