Passi tas-Soluzzjonijiet

Immultiplika \frac{31}{10} b'\frac{3}{10} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{31\times 3}{10\times 10}+\frac{\frac{1}{5}}{\frac{1}{20}}$$

Agħmel il-multiplikazzjonijiet fil-frazzjoni \frac{31\times 3}{10\times 10}.

$$\frac{93}{100}+\frac{\frac{1}{5}}{\frac{1}{20}}$$

Iddividi \frac{1}{5} b'\frac{1}{20} billi timmultiplika \frac{1}{5} bir-reċiproku ta' \frac{1}{20}.

$$\frac{93}{100}+\frac{1}{5}\times 20$$

Immultiplika \frac{1}{5} u 20 biex tikseb \frac{20}{5}.

$$\frac{93}{100}+\frac{20}{5}$$

Iddividi 20 b'5 biex tikseb4.

$$\frac{93}{100}+4$$

Ikkonverti 4 fi frazzjoni \frac{400}{100}.

$$\frac{93}{100}+\frac{400}{100}$$

Billi \frac{93}{100} u \frac{400}{100} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{93+400}{100}$$

Żid 93 u 400 biex tikseb 493.

$$\frac{493}{100}$$

Fattur

$$\frac{17 \cdot 29}{2 ^ {2} \cdot 5 ^ {2}} = 4\frac{93}{100} = 4.93$$
