Answer 1

Bom dia

(1/3) * (4/6) * (13/2) * (18/13) 

= (4*13*18)/(3*6*2*13) = 4/2 = 2

Answer 2

$\dfrac{1}{3} \cdot \dfrac{4}{6} \cdot \dfrac{13}{2} \cdot \dfrac{18}{13} \\ \\ \dfrac{1 \cdot 4 \cdot 13 \cdot 18}{3 \cdot 6 \cdot 2 \cdot 13} \\ \\ \dfrac{13}{13} \cdot \dfrac{18}{6} \cdot \dfrac{4}{2} \cdot \dfrac{1}{3} \\ \\ 1 \cdot 3 \cdot 2 \cdot \dfrac{1}{3} \\ \\ \dfrac{1 \cdot 3 \cdot 2 \cdot 1}{3} \\ \\ \dfrac{3}{3} \cdot 2 \cdot 1 \cdot 1 \\ \\ 1 \cdot 2 \\ \\ 2$
