Koraki rešitve

Delite \frac{3\times 2+3}{2} s/z \frac{1\times 7+1}{7} tako, da pomnožite \frac{3\times 2+3}{2} z obratno vrednostjo \frac{1\times 7+1}{7}.

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

Pomnožite 3 in 2, da dobite 6.

$$\frac{\left(6+3\right)\times 7}{2\left(1\times 7+1\right)}$$

Seštejte 6 in 3, da dobite 9.

$$\frac{9\times 7}{2\left(1\times 7+1\right)}$$

Pomnožite 9 in 7, da dobite 63.

$$\frac{63}{2\left(1\times 7+1\right)}$$

Pomnožite 1 in 7, da dobite 7.

$$\frac{63}{2\left(7+1\right)}$$

Seštejte 7 in 1, da dobite 8.

$$\frac{63}{2\times 8}$$

Pomnožite 2 in 8, da dobite 16.

$$\frac{63}{16}$$
