\frac{0,23}{2} kasrini uning surat va maxrajini 100 ga ko‘paytirish bilan kengaytiring.

$$\frac{\frac{23}{200}-0,05}{0,4}-1$$

0,05 o‘nlik raqamni uning \frac{5}{100} kasrga o‘giring. \frac{5}{100} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{\frac{23}{200}-\frac{1}{20}}{0,4}-1$$
