Passi tas-Soluzzjonijiet

Iddividi \frac{2\times 12+1}{12} b'\frac{5\times 8+5}{8} billi timmultiplika \frac{2\times 12+1}{12} bir-reċiproku ta' \frac{5\times 8+5}{8}.

$$\frac{\left(2\times 12+1\right)\times 8}{12\left(5\times 8+5\right)}\times \frac{2\times 4+1}{4}$$

Annulla 4 fin-numeratur u d-denominatur.

$$\frac{2\left(1+2\times 12\right)}{3\left(5+5\times 8\right)}\times \frac{2\times 4+1}{4}$$

Immultiplika 2 u 12 biex tikseb 24.

$$\frac{2\left(1+24\right)}{3\left(5+5\times 8\right)}\times \frac{2\times 4+1}{4}$$

Żid 1 u 24 biex tikseb 25.

$$\frac{2\times 25}{3\left(5+5\times 8\right)}\times \frac{2\times 4+1}{4}$$

Immultiplika 2 u 25 biex tikseb 50.

$$\frac{50}{3\left(5+5\times 8\right)}\times \frac{2\times 4+1}{4}$$

Immultiplika 5 u 8 biex tikseb 40.

$$\frac{50}{3\left(5+40\right)}\times \frac{2\times 4+1}{4}$$

Żid 5 u 40 biex tikseb 45.

$$\frac{50}{3\times 45}\times \frac{2\times 4+1}{4}$$

Immultiplika 3 u 45 biex tikseb 135.

$$\frac{50}{135}\times \frac{2\times 4+1}{4}$$

Naqqas il-frazzjoni \frac{50}{135} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 5.

$$\frac{10}{27}\times \frac{2\times 4+1}{4}$$

Immultiplika 2 u 4 biex tikseb 8.

$$\frac{10}{27}\times \frac{8+1}{4}$$

Żid 8 u 1 biex tikseb 9.

$$\frac{10}{27}\times \frac{9}{4}$$

Immultiplika \frac{10}{27} b'\frac{9}{4} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{10\times 9}{27\times 4}$$

Agħmel il-multiplikazzjonijiet fil-frazzjoni \frac{10\times 9}{27\times 4}.

$$\frac{90}{108}$$

Naqqas il-frazzjoni \frac{90}{108} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 18.
