Passi tas-Soluzzjonijiet

Iddividi \frac{\frac{30}{210}}{\frac{35}{210}} b'\frac{42}{210} billi timmultiplika \frac{\frac{30}{210}}{\frac{35}{210}} bir-reċiproku ta' \frac{42}{210}.

$$\frac{\frac{30}{210}\times 210}{\frac{35}{210}\times 42}$$

Naqqas il-frazzjoni \frac{30}{210} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 30.

$$\frac{\frac{1}{7}\times 210}{\frac{35}{210}\times 42}$$

Immultiplika \frac{1}{7} u 210 biex tikseb \frac{210}{7}.

$$\frac{\frac{210}{7}}{\frac{35}{210}\times 42}$$

Iddividi 210 b'7 biex tikseb30.

$$\frac{30}{\frac{35}{210}\times 42}$$

Naqqas il-frazzjoni \frac{35}{210} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 35.

$$\frac{30}{\frac{1}{6}\times 42}$$

Immultiplika \frac{1}{6} u 42 biex tikseb \frac{42}{6}.

$$\frac{30}{\frac{42}{6}}$$

Iddividi 42 b'6 biex tikseb7.

$$\frac{30}{7}$$

Fattur

$$\frac{2 \cdot 3 \cdot 5}{7} = 4\frac{2}{7} = 4.285714285714286$$
