Passi tas-Soluzzjonijiet

Immultiplika \frac{7}{10} b'\frac{11}{7} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{7\times 11}{10\times 7}\times \frac{3\times 3+1}{3}\times 2$$

Annulla 7 fin-numeratur u d-denominatur.

$$\frac{11}{10}\times \frac{3\times 3+1}{3}\times 2$$

Immultiplika 3 u 3 biex tikseb 9.

$$\frac{11}{10}\times \frac{9+1}{3}\times 2$$

Żid 9 u 1 biex tikseb 10.

$$\frac{11}{10}\times \frac{10}{3}\times 2$$

Immultiplika \frac{11}{10} b'\frac{10}{3} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$\frac{11\times 10}{10\times 3}\times 2$$

Annulla 10 fin-numeratur u d-denominatur.

$$\frac{11}{3}\times 2$$

Esprimi \frac{11}{3}\times 2 bħala frazzjoni waħda.

$$\frac{11\times 2}{3}$$

Immultiplika 11 u 2 biex tikseb 22.

$$\frac{22}{3}$$

Fattur

$$\frac{2 \cdot 11}{3} = 7\frac{1}{3} = 7.333333333333333$$
