Passi tas-Soluzzjonijiet

L-inqas multipli komuni ta' 10 u 12 huwa 60. Ikkonverti \frac{1}{10} u \frac{1}{12} fi frazzjonijiet bid-denominatur 60.

$$\left(\frac{6}{60}-\frac{5}{60}\right)\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

Billi \frac{6}{60} u \frac{5}{60} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{6-5}{60}\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

Naqqas 5 minn 6 biex tikseb 1.

$$\frac{1}{60}\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

Immultiplika 5 u 4 biex tikseb 20.

$$\frac{1}{60}\left(\frac{20+1}{4}+0\times 75\right)$$

Żid 20 u 1 biex tikseb 21.

$$\frac{1}{60}\left(\frac{21}{4}+0\times 75\right)$$

Immultiplika 0 u 75 biex tikseb 0.

$$\frac{1}{60}\left(\frac{21}{4}+0\right)$$

Żid \frac{21}{4} u 0 biex tikseb \frac{21}{4}.

$$\frac{1}{60}\times \frac{21}{4}$$

Immultiplika \frac{1}{60} b'\frac{21}{4} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{1\times 21}{60\times 4}$$

Agħmel il-multiplikazzjonijiet fil-frazzjoni \frac{1\times 21}{60\times 4}.

$$\frac{21}{240}$$

Naqqas il-frazzjoni \frac{21}{240} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 3.

$$\frac{7}{80}$$

Fattur

$$\frac{7}{2 ^ {4} \cdot 5} = 0.0875$$
