Koraki rešitve

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

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

Pomnožite 2 in 3, da dobite 6.

$$\frac{\left(6+2\right)\times 5}{3\left(1\times 5+2\right)}$$

Seštejte 6 in 2, da dobite 8.

$$\frac{8\times 5}{3\left(1\times 5+2\right)}$$

Pomnožite 8 in 5, da dobite 40.

$$\frac{40}{3\left(1\times 5+2\right)}$$

Pomnožite 1 in 5, da dobite 5.

$$\frac{40}{3\left(5+2\right)}$$

Seštejte 5 in 2, da dobite 7.

$$\frac{40}{3\times 7}$$

Pomnožite 3 in 7, da dobite 21.

$$\frac{40}{21}$$
