Passi tas-Soluzzjonijiet

Immultiplika 3 u 110 biex tikseb 330.

$$\frac{330+1}{110}-\left(\frac{2\times 110+1}{110}+\frac{1}{110}\right)$$

Żid 330 u 1 biex tikseb 331.

$$\frac{331}{110}-\left(\frac{2\times 110+1}{110}+\frac{1}{110}\right)$$

Immultiplika 2 u 110 biex tikseb 220.

$$\frac{331}{110}-\left(\frac{220+1}{110}+\frac{1}{110}\right)$$

Żid 220 u 1 biex tikseb 221.

$$\frac{331}{110}-\left(\frac{221}{110}+\frac{1}{110}\right)$$

Billi \frac{221}{110} u \frac{1}{110} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{331}{110}-\frac{221+1}{110}$$

Żid 221 u 1 biex tikseb 222.

$$\frac{331}{110}-\frac{222}{110}$$

Billi \frac{331}{110} u \frac{222}{110} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{331-222}{110}$$

Naqqas 222 minn 331 biex tikseb 109.

$$\frac{109}{110}$$

Fattur

$$\frac{109}{2 \cdot 5 \cdot 11} = 0.990909090909091$$
