1.2/0.22=x/1.3 eching

$$\frac { 1.2 } { 0.22 } = \frac { x } { 1.3 }$$

x uchun yechish

$$x = \frac{78}{11} = 7\frac{1}{11} \approx 7,090909091$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{1,2}{0,22} kasrini uning surat va maxrajini 100 ga ko‘paytirish bilan kengaytiring.

$$\frac{120}{22}=\frac{x}{1,3}$$

\frac{120}{22} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{60}{11}=\frac{x}{1,3}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$\frac{x}{1,3}=\frac{60}{11}$$

Ikkala tarafini 1,3 ga ko‘paytiring.

$$x=\frac{60}{11}\times 1,3$$

1,3 o‘nlik raqamni uning \frac{13}{10} kasrga o‘giring.

$$x=\frac{60}{11}\times \frac{13}{10}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{60}{11} ni \frac{13}{10} ga ko‘paytiring.

$$x=\frac{60\times 13}{11\times 10}$$

\frac{60\times 13}{11\times 10} kasridagi ko‘paytirishlarni bajaring.

$$x=\frac{780}{110}$$

\frac{780}{110} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{78}{11}$$
