Yechim qadamlari

6 ni olish uchun 30 ni 5 ga bo‘ling.

$$127-\left(6+\frac{42\times 6+2}{6}\right)$$

252 hosil qilish uchun 42 va 6 ni ko'paytirish.

$$127-\left(6+\frac{252+2}{6}\right)$$

254 olish uchun 252 va 2'ni qo'shing.

$$127-\left(6+\frac{254}{6}\right)$$

\frac{254}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$127-\left(6+\frac{127}{3}\right)$$

6 ni \frac{18}{3} kasrga o‘giring.

$$127-\left(\frac{18}{3}+\frac{127}{3}\right)$$

\frac{18}{3} va \frac{127}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$127-\frac{18+127}{3}$$

145 olish uchun 18 va 127'ni qo'shing.

$$127-\frac{145}{3}$$

127 ni \frac{381}{3} kasrga o‘giring.

$$\frac{381}{3}-\frac{145}{3}$$

\frac{381}{3} va \frac{145}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{381-145}{3}$$

236 olish uchun 381 dan 145 ni ayirish.

$$\frac{236}{3}$$

Omil

$$\frac{2 ^ {2} \cdot 59}{3} = 78\frac{2}{3} = 78,66666666666667$$
