Passi tas-Soluzzjonijiet

Esprimi \frac{\frac{2\times 9+3}{9}}{3} bħala frazzjoni waħda.

$$\left(\frac{\left(\frac{2\times 9+3}{9\times 3}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \frac{2}{5}}\right)^{-1}$$

Immultiplika 2 u 9 biex tikseb 18.

$$\left(\frac{\left(\frac{18+3}{9\times 3}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \frac{2}{5}}\right)^{-1}$$

Żid 18 u 3 biex tikseb 21.

$$\left(\frac{\left(\frac{21}{9\times 3}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \frac{2}{5}}\right)^{-1}$$

Immultiplika 9 u 3 biex tikseb 27.

$$\left(\frac{\left(\frac{21}{27}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \frac{2}{5}}\right)^{-1}$$

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

$$\left(\frac{\left(\frac{7}{9}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \frac{2}{5}}\right)^{-1}$$

Ikkalkula \frac{7}{9} bil-power ta' -2 u tikseb \frac{81}{49}.

$$\left(\frac{\frac{81}{49}}{\left(\frac{9}{4}\right)^{2}\times \frac{2}{5}}\right)^{-1}$$

Ikkalkula \frac{9}{4} bil-power ta' 2 u tikseb \frac{81}{16}.

$$\left(\frac{\frac{81}{49}}{\frac{81}{16}\times \frac{2}{5}}\right)^{-1}$$

Immultiplika \frac{81}{16} u \frac{2}{5} biex tikseb \frac{81}{40}.

$$\left(\frac{\frac{81}{49}}{\frac{81}{40}}\right)^{-1}$$

Iddividi \frac{81}{49} b'\frac{81}{40} billi timmultiplika \frac{81}{49} bir-reċiproku ta' \frac{81}{40}.

$$\left(\frac{81}{49}\times \frac{40}{81}\right)^{-1}$$

Immultiplika \frac{81}{49} u \frac{40}{81} biex tikseb \frac{40}{49}.

$$\left(\frac{40}{49}\right)^{-1}$$

Ikkalkula \frac{40}{49} bil-power ta' -1 u tikseb \frac{49}{40}.

$$\frac{49}{40}$$

Fattur

$$\frac{7 ^ {2}}{2 ^ {3} \cdot 5} = 1\frac{9}{40} = 1.225$$
