$$\frac{19.89}{42000000000000000000}-1.6\times 10^{-19}\times 0.75$$

Espandi \frac{19.89}{42000000000000000000} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'100.

$$\frac{1989}{4200000000000000000000}-1.6\times 10^{-19}\times 0.75$$

Naqqas il-frazzjoni \frac{1989}{4200000000000000000000} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 3.

$$\frac{663}{1400000000000000000000}-1.6\times 10^{-19}\times 0.75$$

Ikkalkula 10 bil-power ta' -19 u tikseb \frac{1}{10000000000000000000}.

$$\frac{663}{1400000000000000000000}-1.6\times \frac{1}{10000000000000000000}\times 0.75$$

Immultiplika 1.6 u \frac{1}{10000000000000000000} biex tikseb \frac{1}{6250000000000000000}.

$$\frac{663}{1400000000000000000000}-\frac{1}{6250000000000000000}\times 0.75$$

Immultiplika \frac{1}{6250000000000000000} u 0.75 biex tikseb \frac{3}{25000000000000000000}.

$$\frac{663}{1400000000000000000000}-\frac{3}{25000000000000000000}$$

Naqqas \frac{3}{25000000000000000000} minn \frac{663}{1400000000000000000000} biex tikseb \frac{99}{280000000000000000000}.
