Passi tas-Soluzzjonijiet

Immultiplika 3 u 11 biex tikseb 33.

$$\frac{33+7}{11}-\frac{28}{19}+\frac{15}{31}$$

Żid 33 u 7 biex tikseb 40.

$$\frac{40}{11}-\frac{28}{19}+\frac{15}{31}$$

L-inqas multipli komuni ta' 11 u 19 huwa 209. Ikkonverti \frac{40}{11} u \frac{28}{19} fi frazzjonijiet bid-denominatur 209.

$$\frac{760}{209}-\frac{308}{209}+\frac{15}{31}$$

Billi \frac{760}{209} u \frac{308}{209} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{760-308}{209}+\frac{15}{31}$$

Naqqas 308 minn 760 biex tikseb 452.

$$\frac{452}{209}+\frac{15}{31}$$

L-inqas multipli komuni ta' 209 u 31 huwa 6479. Ikkonverti \frac{452}{209} u \frac{15}{31} fi frazzjonijiet bid-denominatur 6479.

$$\frac{14012}{6479}+\frac{3135}{6479}$$

Billi \frac{14012}{6479} u \frac{3135}{6479} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{14012+3135}{6479}$$

Żid 14012 u 3135 biex tikseb 17147.

$$\frac{17147}{6479}$$

Fattur

$$\frac{13 \cdot 1319}{11 \cdot 19 \cdot 31} = 2\frac{4189}{6479} = 2.6465503935792563$$
