Passi tas-Soluzzjonijiet

Naqqas 8 minn 13 biex tikseb 5.

$$60+2\left(7+\frac{18}{5}\right)-\left(7\times 3-18-2+13\right)$$

Ikkonverti 7 fi frazzjoni \frac{35}{5}.

$$60+2\left(\frac{35}{5}+\frac{18}{5}\right)-\left(7\times 3-18-2+13\right)$$

Billi \frac{35}{5} u \frac{18}{5} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$60+2\times \frac{35+18}{5}-\left(7\times 3-18-2+13\right)$$

Żid 35 u 18 biex tikseb 53.

$$60+2\times \frac{53}{5}-\left(7\times 3-18-2+13\right)$$

Esprimi 2\times \frac{53}{5} bħala frazzjoni waħda.

$$60+\frac{2\times 53}{5}-\left(7\times 3-18-2+13\right)$$

Immultiplika 2 u 53 biex tikseb 106.

$$60+\frac{106}{5}-\left(7\times 3-18-2+13\right)$$

Ikkonverti 60 fi frazzjoni \frac{300}{5}.

$$\frac{300}{5}+\frac{106}{5}-\left(7\times 3-18-2+13\right)$$

Billi \frac{300}{5} u \frac{106}{5} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{300+106}{5}-\left(7\times 3-18-2+13\right)$$

Żid 300 u 106 biex tikseb 406.

$$\frac{406}{5}-\left(7\times 3-18-2+13\right)$$

Immultiplika 7 u 3 biex tikseb 21.

$$\frac{406}{5}-\left(21-18-2+13\right)$$

Naqqas 18 minn 21 biex tikseb 3.

$$\frac{406}{5}-\left(3-2+13\right)$$

Naqqas 2 minn 3 biex tikseb 1.

$$\frac{406}{5}-\left(1+13\right)$$

Żid 1 u 13 biex tikseb 14.

$$\frac{406}{5}-14$$

Ikkonverti 14 fi frazzjoni \frac{70}{5}.

$$\frac{406}{5}-\frac{70}{5}$$

Billi \frac{406}{5} u \frac{70}{5} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{406-70}{5}$$

Naqqas 70 minn 406 biex tikseb 336.

$$\frac{336}{5}$$

Fattur

$$\frac{2 ^ {4} \cdot 3 \cdot 7}{5} = 67\frac{1}{5} = 67.2$$
