12-1/5*9/4*12/6=11/12 eching

$$12 - \frac { 1 } { 5 } \times \frac { 9 } { 4 } \times \frac { 12 } { 6 } = \frac { 11 } { 12 }$$

Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{5} ni \frac{9}{4} ga ko‘paytiring.

$$12-\frac{1\times 9}{5\times 4}\times \frac{12}{6}=\frac{11}{12}$$

\frac{1\times 9}{5\times 4} kasridagi ko‘paytirishlarni bajaring.

$$12-\frac{9}{20}\times \frac{12}{6}=\frac{11}{12}$$

2 ni olish uchun 12 ni 6 ga bo‘ling.

$$12-\frac{9}{20}\times 2=\frac{11}{12}$$

\frac{9}{20}\times 2 ni yagona kasrga aylantiring.

$$12-\frac{9\times 2}{20}=\frac{11}{12}$$

18 hosil qilish uchun 9 va 2 ni ko'paytirish.

$$12-\frac{18}{20}=\frac{11}{12}$$

\frac{18}{20} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$12-\frac{9}{10}=\frac{11}{12}$$

12 ni \frac{120}{10} kasrga o‘giring.

$$\frac{120}{10}-\frac{9}{10}=\frac{11}{12}$$

\frac{120}{10} va \frac{9}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{120-9}{10}=\frac{11}{12}$$

111 olish uchun 120 dan 9 ni ayirish.

$$\frac{111}{10}=\frac{11}{12}$$

10 va 12 ning eng kichik umumiy karralisi 60 ga teng. \frac{111}{10} va \frac{11}{12} ni 60 maxraj bilan kasrlarga aylantirib oling.

$$\frac{666}{60}=\frac{55}{60}$$

\frac{666}{60} va \frac{55}{60} ni taqqoslang.
