Passi tas-Soluzzjonijiet

Iddividi \frac{3\times 4+1}{4} b'\frac{2\times 2+1}{2} billi timmultiplika \frac{3\times 4+1}{4} bir-reċiproku ta' \frac{2\times 2+1}{2}.

$$3-\frac{\left(3\times 4+1\right)\times 2}{4\left(2\times 2+1\right)}+0.3$$

Annulla 2 fin-numeratur u d-denominatur.

$$3-\frac{1+3\times 4}{2\left(1+2\times 2\right)}+0.3$$

Immultiplika 3 u 4 biex tikseb 12.

$$3-\frac{1+12}{2\left(1+2\times 2\right)}+0.3$$

Żid 1 u 12 biex tikseb 13.

$$3-\frac{13}{2\left(1+2\times 2\right)}+0.3$$

Immultiplika 2 u 2 biex tikseb 4.

$$3-\frac{13}{2\left(1+4\right)}+0.3$$

Żid 1 u 4 biex tikseb 5.

$$3-\frac{13}{2\times 5}+0.3$$

Immultiplika 2 u 5 biex tikseb 10.

$$3-\frac{13}{10}+0.3$$

Ikkonverti 3 fi frazzjoni \frac{30}{10}.

$$\frac{30}{10}-\frac{13}{10}+0.3$$

Billi \frac{30}{10} u \frac{13}{10} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{30-13}{10}+0.3$$

Naqqas 13 minn 30 biex tikseb 17.

$$\frac{17}{10}+0.3$$

Ikkonverti n-numru deċimali 0.3 fi frazzjoni \frac{3}{10}.

$$\frac{17}{10}+\frac{3}{10}$$

Billi \frac{17}{10} u \frac{3}{10} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{17+3}{10}$$

Żid 17 u 3 biex tikseb 20.

$$\frac{20}{10}$$

Iddividi 20 b'10 biex tikseb2.
