Yechim qadamlari

14 hosil qilish uchun 1 va 14 ni ko'paytirish.

$$\frac{14+1}{14}-\frac{1\times 14+1}{14}\times \frac{2}{9}$$

15 olish uchun 14 va 1'ni qo'shing.

$$\frac{15}{14}-\frac{1\times 14+1}{14}\times \frac{2}{9}$$

14 hosil qilish uchun 1 va 14 ni ko'paytirish.

$$\frac{15}{14}-\frac{14+1}{14}\times \frac{2}{9}$$

15 olish uchun 14 va 1'ni qo'shing.

$$\frac{15}{14}-\frac{15}{14}\times \frac{2}{9}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{15}{14} ni \frac{2}{9} ga ko‘paytiring.

$$\frac{15}{14}-\frac{15\times 2}{14\times 9}$$

\frac{15\times 2}{14\times 9} kasridagi ko‘paytirishlarni bajaring.

$$\frac{15}{14}-\frac{30}{126}$$

\frac{30}{126} ulushini 6 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{15}{14}-\frac{5}{21}$$

14 va 21 ning eng kichik umumiy karralisi 42 ga teng. \frac{15}{14} va \frac{5}{21} ni 42 maxraj bilan kasrlarga aylantirib oling.

$$\frac{45}{42}-\frac{10}{42}$$

\frac{45}{42} va \frac{10}{42} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{45-10}{42}$$

35 olish uchun 45 dan 10 ni ayirish.

$$\frac{35}{42}$$

\frac{35}{42} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
