Yechim qadamlari

\frac{5}{6} ni \frac{2}{3} ga bo'lish \frac{5}{6} ga k'paytirish \frac{2}{3} ga qaytarish.

$$\frac{5}{6}\times \frac{3}{2}-\frac{4}{9}\times \frac{3}{8}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{5}{6} ni \frac{3}{2} ga ko‘paytiring.

$$\frac{5\times 3}{6\times 2}-\frac{4}{9}\times \frac{3}{8}$$

\frac{5\times 3}{6\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{15}{12}-\frac{4}{9}\times \frac{3}{8}$$

\frac{15}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{4}-\frac{4}{9}\times \frac{3}{8}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{4}{9} ni \frac{3}{8} ga ko‘paytiring.

$$\frac{5}{4}-\frac{4\times 3}{9\times 8}$$

\frac{4\times 3}{9\times 8} kasridagi ko‘paytirishlarni bajaring.

$$\frac{5}{4}-\frac{12}{72}$$

\frac{12}{72} ulushini 12 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{4}-\frac{1}{6}$$

4 va 6 ning eng kichik umumiy karralisi 12 ga teng. \frac{5}{4} va \frac{1}{6} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{15}{12}-\frac{2}{12}$$

\frac{15}{12} va \frac{2}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{15-2}{12}$$

13 olish uchun 15 dan 2 ni ayirish.

$$\frac{13}{12}$$

Omil

$$\frac{13}{2 ^ {2} \cdot 3} = 1\frac{1}{12} = 1,0833333333333333$$
