Yechim qadamlari

135 hosil qilish uchun 27 va 5 ni ko'paytirish.

$$\frac{135}{125}-4\times 9\times 3$$

\frac{135}{125} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{27}{25}-4\times 9\times 3$$

36 hosil qilish uchun 4 va 9 ni ko'paytirish.

$$\frac{27}{25}-36\times 3$$

108 hosil qilish uchun 36 va 3 ni ko'paytirish.

$$\frac{27}{25}-108$$

108 ni \frac{2700}{25} kasrga o‘giring.

$$\frac{27}{25}-\frac{2700}{25}$$

\frac{27}{25} va \frac{2700}{25} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{27-2700}{25}$$

-2673 olish uchun 27 dan 2700 ni ayirish.

$$-\frac{2673}{25}$$

Omil

$$-\frac{2673}{25} = -106\frac{23}{25} = -106,92$$
