Yechim qadamlari

42 hosil qilish uchun 7 va 6 ni ko'paytirish.

$$\frac{42+1}{6}-\frac{5}{18}-1,5$$

43 olish uchun 42 va 1'ni qo'shing.

$$\frac{43}{6}-\frac{5}{18}-1,5$$

6 va 18 ning eng kichik umumiy karralisi 18 ga teng. \frac{43}{6} va \frac{5}{18} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$\frac{129}{18}-\frac{5}{18}-1,5$$

\frac{129}{18} va \frac{5}{18} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{129-5}{18}-1,5$$

124 olish uchun 129 dan 5 ni ayirish.

$$\frac{124}{18}-1,5$$

\frac{124}{18} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{62}{9}-1,5$$

1,5 o‘nlik raqamni uning \frac{15}{10} kasrga o‘giring. \frac{15}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{62}{9}-\frac{3}{2}$$

9 va 2 ning eng kichik umumiy karralisi 18 ga teng. \frac{62}{9} va \frac{3}{2} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$\frac{124}{18}-\frac{27}{18}$$

\frac{124}{18} va \frac{27}{18} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{124-27}{18}$$

97 olish uchun 124 dan 27 ni ayirish.

$$\frac{97}{18}$$

Omil

$$\frac{97}{2 \cdot 3 ^ {2}} = 5\frac{7}{18} = 5,388888888888889$$
