Passi tas-Soluzzjonijiet

Esprimi \frac{\frac{1}{2}}{4} bħala frazzjoni waħda.

$$2-\left(\frac{1}{2\times 4}-6^{0}+5+\frac{2^{2}}{0.3}\right)$$

Immultiplika 2 u 4 biex tikseb 8.

$$2-\left(\frac{1}{8}-6^{0}+5+\frac{2^{2}}{0.3}\right)$$

Ikkalkula 6 bil-power ta' 0 u tikseb 1.

$$2-\left(\frac{1}{8}-1+5+\frac{2^{2}}{0.3}\right)$$

Naqqas 1 minn \frac{1}{8} biex tikseb -\frac{7}{8}.

$$2-\left(-\frac{7}{8}+5+\frac{2^{2}}{0.3}\right)$$

Żid -\frac{7}{8} u 5 biex tikseb \frac{33}{8}.

$$2-\left(\frac{33}{8}+\frac{2^{2}}{0.3}\right)$$

Ikkalkula 2 bil-power ta' 2 u tikseb 4.

$$2-\left(\frac{33}{8}+\frac{4}{0.3}\right)$$

Espandi \frac{4}{0.3} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$2-\left(\frac{33}{8}+\frac{40}{3}\right)$$

Żid \frac{33}{8} u \frac{40}{3} biex tikseb \frac{419}{24}.

$$2-\frac{419}{24}$$

Naqqas \frac{419}{24} minn 2 biex tikseb -\frac{371}{24}.

$$-\frac{371}{24}$$

Fattur

$$-\frac{371}{24} = -15\frac{11}{24} = -15.458333333333334$$
