Yechim qadamlari

4 va 12 ning eng kichik umumiy karralisi 12 ga teng. \frac{1}{4} va \frac{5}{12} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$144\left(\frac{3}{12}-\frac{5}{12}\right)$$

\frac{3}{12} va \frac{5}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$144\times \frac{3-5}{12}$$

-2 olish uchun 3 dan 5 ni ayirish.

$$144\times \frac{-2}{12}$$

\frac{-2}{12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$144\left(-\frac{1}{6}\right)$$

144\left(-\frac{1}{6}\right) ni yagona kasrga aylantiring.

$$\frac{144\left(-1\right)}{6}$$

-144 hosil qilish uchun 144 va -1 ni ko'paytirish.

$$\frac{-144}{6}$$

-24 ni olish uchun -144 ni 6 ga bo‘ling.
