Passi tas-Soluzzjonijiet

Immultiplika 7 u 2 biex tikseb 14.

$$\frac{\frac{14+1}{2}}{1}\times 2-\left(12\left(\frac{1}{3}-0\times 3\right)-\frac{3}{20}\right)$$

Żid 14 u 1 biex tikseb 15.

$$\frac{\frac{15}{2}}{1}\times 2-\left(12\left(\frac{1}{3}-0\times 3\right)-\frac{3}{20}\right)$$

Kwalunkwe ħaġa diviża b'wieħed tagħti riżultat tagħha stess.

$$\frac{15}{2}\times 2-\left(12\left(\frac{1}{3}-0\times 3\right)-\frac{3}{20}\right)$$

Annulla 2 u 2.

$$15-\left(12\left(\frac{1}{3}-0\times 3\right)-\frac{3}{20}\right)$$

Immultiplika 0 u 3 biex tikseb 0.

$$15-\left(12\left(\frac{1}{3}-0\right)-\frac{3}{20}\right)$$

Naqqas 0 minn \frac{1}{3} biex tikseb \frac{1}{3}.

$$15-\left(12\times \frac{1}{3}-\frac{3}{20}\right)$$

Immultiplika 12 u \frac{1}{3} biex tikseb \frac{12}{3}.

$$15-\left(\frac{12}{3}-\frac{3}{20}\right)$$

Iddividi 12 b'3 biex tikseb4.

$$15-\left(4-\frac{3}{20}\right)$$

Ikkonverti 4 fi frazzjoni \frac{80}{20}.

$$15-\left(\frac{80}{20}-\frac{3}{20}\right)$$

Billi \frac{80}{20} u \frac{3}{20} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$15-\frac{80-3}{20}$$

Naqqas 3 minn 80 biex tikseb 77.

$$15-\frac{77}{20}$$

Ikkonverti 15 fi frazzjoni \frac{300}{20}.

$$\frac{300}{20}-\frac{77}{20}$$

Billi \frac{300}{20} u \frac{77}{20} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{300-77}{20}$$

Naqqas 77 minn 300 biex tikseb 223.

$$\frac{223}{20}$$

Fattur

$$\frac{223}{2 ^ {2} \cdot 5} = 11\frac{3}{20} = 11.15$$
