Passi tas-Soluzzjonijiet

Iddividi \frac{4\times 2+1}{2} b'\frac{2\times 7+4}{7} billi timmultiplika \frac{4\times 2+1}{2} bir-reċiproku ta' \frac{2\times 7+4}{7}.

$$\frac{\left(4\times 2+1\right)\times 7}{2\left(2\times 7+4\right)}$$

Immultiplika 4 u 2 biex tikseb 8.

$$\frac{\left(8+1\right)\times 7}{2\left(2\times 7+4\right)}$$

Żid 8 u 1 biex tikseb 9.

$$\frac{9\times 7}{2\left(2\times 7+4\right)}$$

Immultiplika 9 u 7 biex tikseb 63.

$$\frac{63}{2\left(2\times 7+4\right)}$$

Immultiplika 2 u 7 biex tikseb 14.

$$\frac{63}{2\left(14+4\right)}$$

Żid 14 u 4 biex tikseb 18.

$$\frac{63}{2\times 18}$$

Immultiplika 2 u 18 biex tikseb 36.

$$\frac{63}{36}$$

Naqqas il-frazzjoni \frac{63}{36} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 9.

$$\frac{7}{4}$$

Fattur

$$\frac{7}{2 ^ {2}} = 1\frac{3}{4} = 1.75$$
