42/35-(211/35-2/35) eching

$$4 \frac { 2 } { 35 } - ( 2 \frac { 11 } { 35 } - \frac { 2 } { 35 } )$$

Baholash

$$\frac{9}{5}=1,8$$

Yechim qadamlari

140 hosil qilish uchun 4 va 35 ni ko'paytirish.

$$\frac{140+2}{35}-\left(\frac{2\times 35+11}{35}-\frac{2}{35}\right)$$

142 olish uchun 140 va 2'ni qo'shing.

$$\frac{142}{35}-\left(\frac{2\times 35+11}{35}-\frac{2}{35}\right)$$

70 hosil qilish uchun 2 va 35 ni ko'paytirish.

$$\frac{142}{35}-\left(\frac{70+11}{35}-\frac{2}{35}\right)$$

81 olish uchun 70 va 11'ni qo'shing.

$$\frac{142}{35}-\left(\frac{81}{35}-\frac{2}{35}\right)$$

\frac{81}{35} va \frac{2}{35} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{142}{35}-\frac{81-2}{35}$$

79 olish uchun 81 dan 2 ni ayirish.

$$\frac{142}{35}-\frac{79}{35}$$

\frac{142}{35} va \frac{79}{35} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{142-79}{35}$$

63 olish uchun 142 dan 79 ni ayirish.

$$\frac{63}{35}$$

\frac{63}{35} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{5}$$

Omil

$$\frac{3 ^ {2}}{5} = 1\frac{4}{5} = 1,8$$
