$$-0.036+\frac{-0.918}{2}$$

Espandi \frac{-0.918}{2} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'1000.

$$-0.036+\frac{-918}{2000}$$

Naqqas il-frazzjoni \frac{-918}{2000} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$-0.036-\frac{459}{1000}$$

Ikkonverti n-numru deċimali -0.036 fi frazzjoni -\frac{36}{1000}. Naqqas il-frazzjoni -\frac{36}{1000} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 4.

$$-\frac{9}{250}-\frac{459}{1000}$$
