Baholash

$$-\frac{21}{5}=-4,2$$

Yechim qadamlari

40 hosil qilish uchun 4 va 10 ni ko'paytirish.

$$\frac{1}{10}-\frac{40+3}{10}$$

43 olish uchun 40 va 3'ni qo'shing.

$$\frac{1}{10}-\frac{43}{10}$$

\frac{1}{10} va \frac{43}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1-43}{10}$$

-42 olish uchun 1 dan 43 ni ayirish.
