1/2-1/10=1/10-1/10= eching

$$\frac { 1 } { 2 } - \frac { 1 } { 10 } = \frac { 1 } { 10 } - \frac { 1 } { 10 } =$$

Yechim qadamlari

2 va 10 ning eng kichik umumiy karralisi 10 ga teng. \frac{1}{2} va \frac{1}{10} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{5}{10}-\frac{1}{10}=\frac{1}{10}-\frac{1}{10}$$

\frac{5}{10} va \frac{1}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{5-1}{10}=\frac{1}{10}-\frac{1}{10}$$

4 olish uchun 5 dan 1 ni ayirish.

$$\frac{4}{10}=\frac{1}{10}-\frac{1}{10}$$

\frac{4}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{2}{5}=\frac{1}{10}-\frac{1}{10}$$

0 olish uchun \frac{1}{10} dan \frac{1}{10} ni ayirish.

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

\frac{2}{5} va 0 ni taqqoslang.

$$\text{false}$$
