Yechim qadamlari

27 hosil qilish uchun 3 va 9 ni ko'paytirish.

$$\frac{27+1}{9}+\frac{1\times 8+1}{8}$$

28 olish uchun 27 va 1'ni qo'shing.

$$\frac{28}{9}+\frac{1\times 8+1}{8}$$

8 hosil qilish uchun 1 va 8 ni ko'paytirish.

$$\frac{28}{9}+\frac{8+1}{8}$$

9 olish uchun 8 va 1'ni qo'shing.

$$\frac{28}{9}+\frac{9}{8}$$

9 va 8 ning eng kichik umumiy karralisi 72 ga teng. \frac{28}{9} va \frac{9}{8} ni 72 maxraj bilan kasrlarga aylantirib oling.

$$\frac{224}{72}+\frac{81}{72}$$

\frac{224}{72} va \frac{81}{72} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{224+81}{72}$$

305 olish uchun 224 va 81'ni qo'shing.

$$\frac{305}{72}$$

Omil

$$\frac{5 \cdot 61}{2 ^ {3} \cdot 3 ^ {2}} = 4\frac{17}{72} = 4,236111111111111$$
