Yechim qadamlari

6,8 olish uchun 8,2 dan 1,4 ni ayirish.

$$\frac{6,8+2,2}{0,3}-\left(1,4+0,9\times 0,1\right)$$

9 olish uchun 6,8 va 2,2'ni qo'shing.

$$\frac{9}{0,3}-\left(1,4+0,9\times 0,1\right)$$

\frac{9}{0,3} kasrini uning surat va maxrajini 10 ga ko‘paytirish bilan kengaytiring.

$$\frac{90}{3}-\left(1,4+0,9\times 0,1\right)$$

30 ni olish uchun 90 ni 3 ga bo‘ling.

$$30-\left(1,4+0,9\times 0,1\right)$$

0,09 hosil qilish uchun 0,9 va 0,1 ni ko'paytirish.

$$30-\left(1,4+0,09\right)$$

1,49 olish uchun 1,4 va 0,09'ni qo'shing.

$$30-1,49$$

28,51 olish uchun 30 dan 1,49 ni ayirish.

$$28,51$$
