Yechim qadamlari

90 hosil qilish uchun 10 va 9 ni ko'paytirish.

$$\frac{5}{4}+\frac{90+6}{9}$$

96 olish uchun 90 va 6'ni qo'shing.

$$\frac{5}{4}+\frac{96}{9}$$

\frac{96}{9} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{4}+\frac{32}{3}$$

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. \frac{5}{4} va \frac{32}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{15}{12}+\frac{128}{12}$$

\frac{15}{12} va \frac{128}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{15+128}{12}$$

143 olish uchun 15 va 128'ni qo'shing.

$$\frac{143}{12}$$

Omil

$$\frac{11 \cdot 13}{2 ^ {2} \cdot 3} = 11\frac{11}{12} = 11,916666666666666$$
