Passi tas-Soluzzjonijiet

Ikkonverti 1 fi frazzjoni \frac{10}{10}.

$$\frac{\frac{10}{10}-\frac{1}{10}}{\frac{1}{10}+\frac{1}{8}}$$

Billi \frac{10}{10} u \frac{1}{10} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{\frac{10-1}{10}}{\frac{1}{10}+\frac{1}{8}}$$

Naqqas 1 minn 10 biex tikseb 9.

$$\frac{\frac{9}{10}}{\frac{1}{10}+\frac{1}{8}}$$

L-inqas multipli komuni ta' 10 u 8 huwa 40. Ikkonverti \frac{1}{10} u \frac{1}{8} fi frazzjonijiet bid-denominatur 40.

$$\frac{\frac{9}{10}}{\frac{4}{40}+\frac{5}{40}}$$

Billi \frac{4}{40} u \frac{5}{40} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{\frac{9}{10}}{\frac{4+5}{40}}$$

Żid 4 u 5 biex tikseb 9.

$$\frac{\frac{9}{10}}{\frac{9}{40}}$$

Iddividi \frac{9}{10} b'\frac{9}{40} billi timmultiplika \frac{9}{10} bir-reċiproku ta' \frac{9}{40}.

$$\frac{9}{10}\times \frac{40}{9}$$

Immultiplika \frac{9}{10} b'\frac{40}{9} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{9\times 40}{10\times 9}$$

Annulla 9 fin-numeratur u d-denominatur.

$$\frac{40}{10}$$

Iddividi 40 b'10 biex tikseb4.
