Passi tas-Soluzzjonijiet

Immultiplika \frac{4}{3} b'\frac{3}{5} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{2}{5}+\frac{4\times 3}{3\times 5}-\left(\frac{1}{4}\right)^{2}$$

Annulla 3 fin-numeratur u d-denominatur.

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

Billi \frac{2}{5} u \frac{4}{5} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

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

Żid 2 u 4 biex tikseb 6.

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

Ikkalkula \frac{1}{4} bil-power ta' 2 u tikseb \frac{1}{16}.

$$\frac{6}{5}-\frac{1}{16}$$

L-inqas multipli komuni ta' 5 u 16 huwa 80. Ikkonverti \frac{6}{5} u \frac{1}{16} fi frazzjonijiet bid-denominatur 80.

$$\frac{96}{80}-\frac{5}{80}$$

Billi \frac{96}{80} u \frac{5}{80} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{96-5}{80}$$

Naqqas 5 minn 96 biex tikseb 91.

$$\frac{91}{80}$$

Fattur

$$\frac{7 \cdot 13}{2 ^ {4} \cdot 5} = 1\frac{11}{80} = 1.1375$$
