31/110-(21/110+1/110) eching

$$3 \frac { 1 } { 110 } - ( 2 \frac { 1 } { 110 } + \frac { 1 } { 110 } )$$

Baholash

$$\frac{109}{110}\approx 0,990909091$$

Yechim qadamlari

330 hosil qilish uchun 3 va 110 ni ko'paytirish.

$$\frac{330+1}{110}-\left(\frac{2\times 110+1}{110}+\frac{1}{110}\right)$$

331 olish uchun 330 va 1'ni qo'shing.

$$\frac{331}{110}-\left(\frac{2\times 110+1}{110}+\frac{1}{110}\right)$$

220 hosil qilish uchun 2 va 110 ni ko'paytirish.

$$\frac{331}{110}-\left(\frac{220+1}{110}+\frac{1}{110}\right)$$

221 olish uchun 220 va 1'ni qo'shing.

$$\frac{331}{110}-\left(\frac{221}{110}+\frac{1}{110}\right)$$

\frac{221}{110} va \frac{1}{110} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{331}{110}-\frac{221+1}{110}$$

222 olish uchun 221 va 1'ni qo'shing.

$$\frac{331}{110}-\frac{222}{110}$$

\frac{331}{110} va \frac{222}{110} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{331-222}{110}$$

109 olish uchun 331 dan 222 ni ayirish.

$$\frac{109}{110}$$

Omil

$$\frac{109}{2 \cdot 5 \cdot 11} = 0,990909090909091$$
