Yechim qadamlari

64 hosil qilish uchun 16 va 4 ni ko'paytirish.

$$\frac{64+5}{4}+\frac{9\times 2+3}{2}$$

69 olish uchun 64 va 5'ni qo'shing.

$$\frac{69}{4}+\frac{9\times 2+3}{2}$$

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

$$\frac{69}{4}+\frac{18+3}{2}$$

21 olish uchun 18 va 3'ni qo'shing.

$$\frac{69}{4}+\frac{21}{2}$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{69}{4} va \frac{21}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{69}{4}+\frac{42}{4}$$

\frac{69}{4} va \frac{42}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{69+42}{4}$$

111 olish uchun 69 va 42'ni qo'shing.

$$\frac{111}{4}$$

Omil

$$\frac{3 \cdot 37}{2 ^ {2}} = 27\frac{3}{4} = 27,75$$
