Yechim qadamlari

-1 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{10} ni qiymatni oling.

$$432\times \frac{1}{10}-25\times 10^{-1}\times 115$$

\frac{216}{5} hosil qilish uchun 432 va \frac{1}{10} ni ko'paytirish.

$$\frac{216}{5}-25\times 10^{-1}\times 115$$

-1 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{10} ni qiymatni oling.

$$\frac{216}{5}-25\times \frac{1}{10}\times 115$$

\frac{5}{2} hosil qilish uchun 25 va \frac{1}{10} ni ko'paytirish.

$$\frac{216}{5}-\frac{5}{2}\times 115$$

\frac{575}{2} hosil qilish uchun \frac{5}{2} va 115 ni ko'paytirish.

$$\frac{216}{5}-\frac{575}{2}$$

-\frac{2443}{10} olish uchun \frac{216}{5} dan \frac{575}{2} ni ayirish.

$$-\frac{2443}{10}$$

Omil

$$-\frac{2443}{10} = -244\frac{3}{10} = -244,3$$
