4/25*3/4-1/50 eching

$$\frac { 4 } { 25 } \times \frac { 3 } { 4 } - \frac { 1 } { 50 }$$

Baholash

$$\frac{1}{10}=0,1$$

Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{4}{25} ni \frac{3}{4} ga ko‘paytiring.

$$\frac{4\times 3}{25\times 4}-\frac{1}{50}$$

Surat va maxrajdagi ikkala 4 ni qisqartiring.

$$\frac{3}{25}-\frac{1}{50}$$

25 va 50 ning eng kichik umumiy karralisi 50 ga teng. \frac{3}{25} va \frac{1}{50} ni 50 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{50}-\frac{1}{50}$$

\frac{6}{50} va \frac{1}{50} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{6-1}{50}$$

5 olish uchun 6 dan 1 ni ayirish.

$$\frac{5}{50}$$

\frac{5}{50} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{10}$$

Omil

$$\frac{1}{2 \cdot 5} = 0,1$$
