Koraki rešitve

Delite \frac{3\times 2+1}{2} s/z \frac{1\times 3+1}{3} tako, da pomnožite \frac{3\times 2+1}{2} z obratno vrednostjo \frac{1\times 3+1}{3}.

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

Pomnožite 3 in 2, da dobite 6.

$$\frac{\left(6+1\right)\times 3}{2\left(1\times 3+1\right)}$$

Seštejte 6 in 1, da dobite 7.

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

Pomnožite 7 in 3, da dobite 21.

$$\frac{21}{2\left(1\times 3+1\right)}$$

Pomnožite 1 in 3, da dobite 3.

$$\frac{21}{2\left(3+1\right)}$$

Seštejte 3 in 1, da dobite 4.

$$\frac{21}{2\times 4}$$

Pomnožite 2 in 4, da dobite 8.

$$\frac{21}{8}$$

Faktoriziraj

$$\frac{3 \cdot 7}{2 ^ {3}} = 2\frac{5}{8} = 2,625$$
