Passi tas-Soluzzjonijiet

Iddividi \frac{1\times 7+4}{7} b'\frac{2\times 3+1}{3} billi timmultiplika \frac{1\times 7+4}{7} bir-reċiproku ta' \frac{2\times 3+1}{3}.

$$\frac{\left(1\times 7+4\right)\times 3}{7\left(2\times 3+1\right)}\times \frac{4\times 22+3}{22}$$

Immultiplika 1 u 7 biex tikseb 7.

$$\frac{\left(7+4\right)\times 3}{7\left(2\times 3+1\right)}\times \frac{4\times 22+3}{22}$$

Żid 7 u 4 biex tikseb 11.

$$\frac{11\times 3}{7\left(2\times 3+1\right)}\times \frac{4\times 22+3}{22}$$

Immultiplika 11 u 3 biex tikseb 33.

$$\frac{33}{7\left(2\times 3+1\right)}\times \frac{4\times 22+3}{22}$$

Immultiplika 2 u 3 biex tikseb 6.

$$\frac{33}{7\left(6+1\right)}\times \frac{4\times 22+3}{22}$$

Żid 6 u 1 biex tikseb 7.

$$\frac{33}{7\times 7}\times \frac{4\times 22+3}{22}$$

Immultiplika 7 u 7 biex tikseb 49.

$$\frac{33}{49}\times \frac{4\times 22+3}{22}$$

Immultiplika 4 u 22 biex tikseb 88.

$$\frac{33}{49}\times \frac{88+3}{22}$$

Żid 88 u 3 biex tikseb 91.

$$\frac{33}{49}\times \frac{91}{22}$$

Immultiplika \frac{33}{49} b'\frac{91}{22} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{33\times 91}{49\times 22}$$

Agħmel il-multiplikazzjonijiet fil-frazzjoni \frac{33\times 91}{49\times 22}.

$$\frac{3003}{1078}$$

Naqqas il-frazzjoni \frac{3003}{1078} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 77.

$$\frac{39}{14}$$

Fattur

$$\frac{3 \cdot 13}{2 \cdot 7} = 2\frac{11}{14} = 2.7857142857142856$$
