Baholash

$$\frac{254}{5}=50,8$$

Yechim qadamlari

50 hosil qilish uchun 5 va 10 ni ko'paytirish.

$$30-\left(1-\frac{50+8}{10}\right)+16$$

58 olish uchun 50 va 8'ni qo'shing.

$$30-\left(1-\frac{58}{10}\right)+16$$

\frac{58}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$30-\left(1-\frac{29}{5}\right)+16$$

1 ni \frac{5}{5} kasrga o‘giring.

$$30-\left(\frac{5}{5}-\frac{29}{5}\right)+16$$

\frac{5}{5} va \frac{29}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$30-\frac{5-29}{5}+16$$

-24 olish uchun 5 dan 29 ni ayirish.

$$30-\left(-\frac{24}{5}\right)+16$$

-\frac{24}{5} ning teskarisi \frac{24}{5} ga teng.

$$30+\frac{24}{5}+16$$

30 ni \frac{150}{5} kasrga o‘giring.

$$\frac{150}{5}+\frac{24}{5}+16$$

\frac{150}{5} va \frac{24}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{150+24}{5}+16$$

174 olish uchun 150 va 24'ni qo'shing.

$$\frac{174}{5}+16$$

16 ni \frac{80}{5} kasrga o‘giring.

$$\frac{174}{5}+\frac{80}{5}$$

\frac{174}{5} va \frac{80}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{174+80}{5}$$

254 olish uchun 174 va 80'ni qo'shing.

$$\frac{254}{5}$$

Omil

$$\frac{2 \cdot 127}{5} = 50\frac{4}{5} = 50,8$$
