Passi tas-Soluzzjonijiet

Esprimi \frac{17}{100}\times 820 bħala frazzjoni waħda.

$$\frac{17\times 820}{100}+\frac{23}{100}\times 820-\frac{10}{100}\times 810$$

Immultiplika 17 u 820 biex tikseb 13940.

$$\frac{13940}{100}+\frac{23}{100}\times 820-\frac{10}{100}\times 810$$

Naqqas il-frazzjoni \frac{13940}{100} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 20.

$$\frac{697}{5}+\frac{23}{100}\times 820-\frac{10}{100}\times 810$$

Esprimi \frac{23}{100}\times 820 bħala frazzjoni waħda.

$$\frac{697}{5}+\frac{23\times 820}{100}-\frac{10}{100}\times 810$$

Immultiplika 23 u 820 biex tikseb 18860.

$$\frac{697}{5}+\frac{18860}{100}-\frac{10}{100}\times 810$$

Naqqas il-frazzjoni \frac{18860}{100} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 20.

$$\frac{697}{5}+\frac{943}{5}-\frac{10}{100}\times 810$$

Billi \frac{697}{5} u \frac{943}{5} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{697+943}{5}-\frac{10}{100}\times 810$$

Żid 697 u 943 biex tikseb 1640.

$$\frac{1640}{5}-\frac{10}{100}\times 810$$

Iddividi 1640 b'5 biex tikseb328.

$$328-\frac{10}{100}\times 810$$

Naqqas il-frazzjoni \frac{10}{100} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 10.

$$328-\frac{1}{10}\times 810$$

Immultiplika \frac{1}{10} u 810 biex tikseb \frac{810}{10}.

$$328-\frac{810}{10}$$

Iddividi 810 b'10 biex tikseb81.

$$328-81$$

Naqqas 81 minn 328 biex tikseb 247.

$$247$$
