Yechim qadamlari

\frac{0,027}{0,003} kasrini uning surat va maxrajini 1000 ga ko‘paytirish bilan kengaytiring.

$$\left(\frac{27}{3}+\frac{0,0016}{0,002}\right)\times \frac{1}{10}$$

9 ni olish uchun 27 ni 3 ga bo‘ling.

$$\left(9+\frac{0,0016}{0,002}\right)\times \frac{1}{10}$$

\frac{0,0016}{0,002} kasrini uning surat va maxrajini 10000 ga ko‘paytirish bilan kengaytiring.

$$\left(9+\frac{16}{20}\right)\times \frac{1}{10}$$

\frac{16}{20} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\left(9+\frac{4}{5}\right)\times \frac{1}{10}$$

9 ni \frac{45}{5} kasrga o‘giring.

$$\left(\frac{45}{5}+\frac{4}{5}\right)\times \frac{1}{10}$$

\frac{45}{5} va \frac{4}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{45+4}{5}\times \frac{1}{10}$$

49 olish uchun 45 va 4'ni qo'shing.

$$\frac{49}{5}\times \frac{1}{10}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{49}{5} ni \frac{1}{10} ga ko‘paytiring.

$$\frac{49\times 1}{5\times 10}$$

\frac{49\times 1}{5\times 10} kasridagi ko‘paytirishlarni bajaring.

$$\frac{49}{50}$$
