Koraki rešitve

Delite \frac{3\times 5+2}{5} s/z \frac{2\times 2+1}{2} tako, da pomnožite \frac{3\times 5+2}{5} z obratno vrednostjo \frac{2\times 2+1}{2}.

$$\frac{\left(3\times 5+2\right)\times 2}{5\left(2\times 2+1\right)}$$

Pomnožite 3 in 5, da dobite 15.

$$\frac{\left(15+2\right)\times 2}{5\left(2\times 2+1\right)}$$

Seštejte 15 in 2, da dobite 17.

$$\frac{17\times 2}{5\left(2\times 2+1\right)}$$

Pomnožite 17 in 2, da dobite 34.

$$\frac{34}{5\left(2\times 2+1\right)}$$

Pomnožite 2 in 2, da dobite 4.

$$\frac{34}{5\left(4+1\right)}$$

Seštejte 4 in 1, da dobite 5.

$$\frac{34}{5\times 5}$$

Pomnožite 5 in 5, da dobite 25.

$$\frac{34}{25}$$
