Anyway, congratulations to Marina, Verónica, Jorge, Xabier, Iván and Tania; you all deserve a Challenge Possitive Extra Point :D

It wasn't that difficult, was it?

a) $0,\widehat{6}+0,\widehat{3}= \frac{6}{9} + \frac{3}{9} = 1$

b)

$$\left(1-\frac{1}{2}\right) \cdot \left( 1-\frac{1}{3} \right) \cdot \left( 1- \frac{1}{4} \right) \cdot \left( 1 - \frac{1}{5} \right) \cdots \left( 1 - \frac{1}{999} \right) \cdot \left( 1 - \frac{1}{1000} \right) = \\ \frac{1}{2} \cdot \frac{2}{3} \cdot \frac{3}{4} \cdot \frac{4}{5} \cdots \frac{998}{999} \cdot \frac{999}{1000} = \frac{1}{1000}$$

$$\left(1-\frac{1}{2}\right) \cdot \left( 1-\frac{1}{3} \right) \cdot \left( 1- \frac{1}{4} \right) \cdot \left( 1 - \frac{1}{5} \right) \cdots \left( 1 - \frac{1}{999} \right) \cdot \left( 1 - \frac{1}{1000} \right) = \\ \frac{1}{2} \cdot \frac{2}{3} \cdot \frac{3}{4} \cdot \frac{4}{5} \cdots \frac{998}{999} \cdot \frac{999}{1000} = \frac{1}{1000}$$
