17/30-1/3-(1/10-1/15) eching

$$\frac { 17 } { 30 } - \frac { 1 } { 3 } - ( \frac { 1 } { 10 } - \frac { 1 } { 15 } )$$

Baholash

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

Yechim qadamlari

30 va 3 ning eng kichik umumiy karralisi 30 ga teng. \frac{17}{30} va \frac{1}{3} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{17}{30}-\frac{10}{30}-\left(\frac{1}{10}-\frac{1}{15}\right)$$

\frac{17}{30} va \frac{10}{30} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{17-10}{30}-\left(\frac{1}{10}-\frac{1}{15}\right)$$

7 olish uchun 17 dan 10 ni ayirish.

$$\frac{7}{30}-\left(\frac{1}{10}-\frac{1}{15}\right)$$

10 va 15 ning eng kichik umumiy karralisi 30 ga teng. \frac{1}{10} va \frac{1}{15} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{7}{30}-\left(\frac{3}{30}-\frac{2}{30}\right)$$

\frac{3}{30} va \frac{2}{30} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{7}{30}-\frac{3-2}{30}$$

1 olish uchun 3 dan 2 ni ayirish.

$$\frac{7}{30}-\frac{1}{30}$$

\frac{7}{30} va \frac{1}{30} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{7-1}{30}$$

6 olish uchun 7 dan 1 ni ayirish.

$$\frac{6}{30}$$

\frac{6}{30} ulushini 6 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{5}$$
