Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{12} ni \frac{1}{12} ga ko‘paytiring.

$$\frac{1\times 1}{12\times 12}\times \frac{3}{2}-\frac{1}{12}$$

\frac{1\times 1}{12\times 12} kasridagi ko‘paytirishlarni bajaring.

$$\frac{1}{144}\times \frac{3}{2}-\frac{1}{12}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{144} ni \frac{3}{2} ga ko‘paytiring.

$$\frac{1\times 3}{144\times 2}-\frac{1}{12}$$

\frac{1\times 3}{144\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{3}{288}-\frac{1}{12}$$

\frac{3}{288} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{96}-\frac{1}{12}$$

96 va 12 ning eng kichik umumiy karralisi 96 ga teng. \frac{1}{96} va \frac{1}{12} ni 96 maxraj bilan kasrlarga aylantirib oling.

$$\frac{1}{96}-\frac{8}{96}$$

\frac{1}{96} va \frac{8}{96} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1-8}{96}$$

-7 olish uchun 1 dan 8 ni ayirish.

$$-\frac{7}{96}$$
