Passi tas-Soluzzjonijiet

Immultiplika 0 u 5 biex tikseb 0.

$$\frac{3}{4}+0-\left(\frac{4}{5}-0\times 2\right)$$

Żid \frac{3}{4} u 0 biex tikseb \frac{3}{4}.

$$\frac{3}{4}-\left(\frac{4}{5}-0\times 2\right)$$

Immultiplika 0 u 2 biex tikseb 0.

$$\frac{3}{4}-\left(\frac{4}{5}-0\right)$$

Naqqas 0 minn \frac{4}{5} biex tikseb \frac{4}{5}.

$$\frac{3}{4}-\frac{4}{5}$$

L-inqas multipli komuni ta' 4 u 5 huwa 20. Ikkonverti \frac{3}{4} u \frac{4}{5} fi frazzjonijiet bid-denominatur 20.

$$\frac{15}{20}-\frac{16}{20}$$

Billi \frac{15}{20} u \frac{16}{20} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{15-16}{20}$$

Naqqas 16 minn 15 biex tikseb -1.

$$-\frac{1}{20}$$

Fattur

$$-\frac{1}{20} = -0.05$$
