Kasrlar yig'indisi

Ikkita oddiy kasr berilgan: $\dfrac{a}{b}$ va $\dfrac{c}{d}$. Ularning yig'indisini qisqarmaydigan kasr $\dfrac{p}{q}$ ko'rinishida toping.

Bitta qatorda to'rtta butun son $a$, $b$, $c$, $d$ ($1 \le a, b, c, d \le 10^4$).

Bitta qatorda ikkita son: $p$ va $q$. Javob butun son bo'lsa ham, $q = 1$ yoziladi.

$\dfrac{a}{b} + \dfrac{c}{d} = \dfrac{ad + cb}{bd}$, keyin surat va maxrajni ularning EKUBiga bo'ling.

Birinchi misolda: $\dfrac{1}{2} + \dfrac{1}{3} = \dfrac{5}{6}$; ikkinchisida $\dfrac{1}{4} + \dfrac{1}{4} = \dfrac{8}{16} = \dfrac{1}{2}$.
