Passi tas-Soluzzjonijiet

Ikkonverti -1 fi frazzjoni -\frac{21}{21}.

$$\frac{-\frac{21}{21}+\frac{22}{21}}{\frac{2}{54}}$$

Billi -\frac{21}{21} u \frac{22}{21} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{\frac{-21+22}{21}}{\frac{2}{54}}$$

Żid -21 u 22 biex tikseb 1.

$$\frac{\frac{1}{21}}{\frac{2}{54}}$$

Naqqas il-frazzjoni \frac{2}{54} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$\frac{\frac{1}{21}}{\frac{1}{27}}$$

Iddividi \frac{1}{21} b'\frac{1}{27} billi timmultiplika \frac{1}{21} bir-reċiproku ta' \frac{1}{27}.

$$\frac{1}{21}\times 27$$

Immultiplika \frac{1}{21} u 27 biex tikseb \frac{27}{21}.

$$\frac{27}{21}$$

Naqqas il-frazzjoni \frac{27}{21} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 3.

$$\frac{9}{7}$$

Fattur

$$\frac{3 ^ {2}}{7} = 1\frac{2}{7} = 1.2857142857142858$$
