Passi tas-Soluzzjonijiet

Naqqas il-frazzjoni \frac{2}{8} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

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

Immultiplika 1 u \frac{1}{4} biex tikseb \frac{1}{4}.

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

Immultiplika 4 u 5 biex tikseb 20.

$$\frac{\frac{1}{4}+20}{\frac{1}{4}\left(6-1\right)}$$

Ikkonverti 20 fi frazzjoni \frac{80}{4}.

$$\frac{\frac{1}{4}+\frac{80}{4}}{\frac{1}{4}\left(6-1\right)}$$

Billi \frac{1}{4} u \frac{80}{4} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{\frac{1+80}{4}}{\frac{1}{4}\left(6-1\right)}$$

Żid 1 u 80 biex tikseb 81.

$$\frac{\frac{81}{4}}{\frac{1}{4}\left(6-1\right)}$$

Naqqas 1 minn 6 biex tikseb 5.

$$\frac{\frac{81}{4}}{\frac{1}{4}\times 5}$$

Immultiplika \frac{1}{4} u 5 biex tikseb \frac{5}{4}.

$$\frac{\frac{81}{4}}{\frac{5}{4}}$$

Iddividi \frac{81}{4} b'\frac{5}{4} billi timmultiplika \frac{81}{4} bir-reċiproku ta' \frac{5}{4}.

$$\frac{81}{4}\times \frac{4}{5}$$

Immultiplika \frac{81}{4} b'\frac{4}{5} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{81\times 4}{4\times 5}$$

Annulla 4 fin-numeratur u d-denominatur.

$$\frac{81}{5}$$

Fattur

$$\frac{3 ^ {4}}{5} = 16\frac{1}{5} = 16.2$$
