2/11*(21/2+1/4) eching

$$\frac { 2 } { 11 } \times ( 2 \frac { 1 } { 2 } + \frac { 1 } { 4 } )$$

Baholash

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

Yechim qadamlari

4 hosil qilish uchun 2 va 2 ni ko'paytirish.

$$\frac{2}{11}\left(\frac{4+1}{2}+\frac{1}{4}\right)$$

5 olish uchun 4 va 1'ni qo'shing.

$$\frac{2}{11}\left(\frac{5}{2}+\frac{1}{4}\right)$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{5}{2} va \frac{1}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{2}{11}\left(\frac{10}{4}+\frac{1}{4}\right)$$

\frac{10}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{2}{11}\times \frac{10+1}{4}$$

11 olish uchun 10 va 1'ni qo'shing.

$$\frac{2}{11}\times \frac{11}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{2}{11} ni \frac{11}{4} ga ko‘paytiring.

$$\frac{2\times 11}{11\times 4}$$

Surat va maxrajdagi ikkala 11 ni qisqartiring.

$$\frac{2}{4}$$

\frac{2}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{2}$$

Omil

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