Passi tas-Soluzzjonijiet

Immultiplika 15 u 5 biex tikseb 75.

$$\frac{75+2}{5}-\frac{6\times 5+3}{5}-\frac{6\times 4+3}{4}$$

Żid 75 u 2 biex tikseb 77.

$$\frac{77}{5}-\frac{6\times 5+3}{5}-\frac{6\times 4+3}{4}$$

Immultiplika 6 u 5 biex tikseb 30.

$$\frac{77}{5}-\frac{30+3}{5}-\frac{6\times 4+3}{4}$$

Żid 30 u 3 biex tikseb 33.

$$\frac{77}{5}-\frac{33}{5}-\frac{6\times 4+3}{4}$$

Billi \frac{77}{5} u \frac{33}{5} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{77-33}{5}-\frac{6\times 4+3}{4}$$

Naqqas 33 minn 77 biex tikseb 44.

$$\frac{44}{5}-\frac{6\times 4+3}{4}$$

Immultiplika 6 u 4 biex tikseb 24.

$$\frac{44}{5}-\frac{24+3}{4}$$

Żid 24 u 3 biex tikseb 27.

$$\frac{44}{5}-\frac{27}{4}$$

L-inqas multipli komuni ta' 5 u 4 huwa 20. Ikkonverti \frac{44}{5} u \frac{27}{4} fi frazzjonijiet bid-denominatur 20.

$$\frac{176}{20}-\frac{135}{20}$$

Billi \frac{176}{20} u \frac{135}{20} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{176-135}{20}$$

Naqqas 135 minn 176 biex tikseb 41.

$$\frac{41}{20}$$

Fattur

$$\frac{41}{2 ^ {2} \cdot 5} = 2\frac{1}{20} = 2.05$$
