1-3/4+5/18 eching

$$1 - \frac { 3 } { 4 } + \frac { 5 } { 18 }$$

Baholash

$$\frac{19}{36}\approx 0,527777778$$

Yechim qadamlari

1 ni \frac{4}{4} kasrga o‘giring.

$$\frac{4}{4}-\frac{3}{4}+\frac{5}{18}$$

\frac{4}{4} va \frac{3}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{4-3}{4}+\frac{5}{18}$$

1 olish uchun 4 dan 3 ni ayirish.

$$\frac{1}{4}+\frac{5}{18}$$

4 va 18 ning eng kichik umumiy karralisi 36 ga teng. \frac{1}{4} va \frac{5}{18} ni 36 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{36}+\frac{10}{36}$$

\frac{9}{36} va \frac{10}{36} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{9+10}{36}$$

19 olish uchun 9 va 10'ni qo'shing.

$$\frac{19}{36}$$

Omil

$$\frac{19}{2 ^ {2} \cdot 3 ^ {2}} = 0,5277777777777778$$
