Yechim qadamlari

3 va 12 ning eng kichik umumiy karralisi 12 ga teng. \frac{1}{3} va \frac{5}{12} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$144\left(\frac{4}{12}+\frac{5}{12}\right)$$

\frac{4}{12} va \frac{5}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$144\times \frac{4+5}{12}$$

9 olish uchun 4 va 5'ni qo'shing.

$$144\times \frac{9}{12}$$

\frac{9}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$144\times \frac{3}{4}$$

144\times \frac{3}{4} ni yagona kasrga aylantiring.

$$\frac{144\times 3}{4}$$

432 hosil qilish uchun 144 va 3 ni ko'paytirish.

$$\frac{432}{4}$$

108 ni olish uchun 432 ni 4 ga bo‘ling.
