Passi tas-Soluzzjonijiet

Immultiplika 4 u 5 biex tikseb 20.

$$\left(\frac{20+2}{5}-2.9\right)\times \frac{6\times 3+1}{3}$$

Żid 20 u 2 biex tikseb 22.

$$\left(\frac{22}{5}-2.9\right)\times \frac{6\times 3+1}{3}$$

Ikkonverti n-numru deċimali 2.9 fi frazzjoni \frac{29}{10}.

$$\left(\frac{22}{5}-\frac{29}{10}\right)\times \frac{6\times 3+1}{3}$$

L-inqas multipli komuni ta' 5 u 10 huwa 10. Ikkonverti \frac{22}{5} u \frac{29}{10} fi frazzjonijiet bid-denominatur 10.

$$\left(\frac{44}{10}-\frac{29}{10}\right)\times \frac{6\times 3+1}{3}$$

Billi \frac{44}{10} u \frac{29}{10} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{44-29}{10}\times \frac{6\times 3+1}{3}$$

Naqqas 29 minn 44 biex tikseb 15.

$$\frac{15}{10}\times \frac{6\times 3+1}{3}$$

Naqqas il-frazzjoni \frac{15}{10} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 5.

$$\frac{3}{2}\times \frac{6\times 3+1}{3}$$

Immultiplika 6 u 3 biex tikseb 18.

$$\frac{3}{2}\times \frac{18+1}{3}$$

Żid 18 u 1 biex tikseb 19.

$$\frac{3}{2}\times \frac{19}{3}$$

Immultiplika \frac{3}{2} b'\frac{19}{3} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{3\times 19}{2\times 3}$$

Annulla 3 fin-numeratur u d-denominatur.

$$\frac{19}{2}$$

Fattur

$$\frac{19}{2} = 9\frac{1}{2} = 9.5$$
