Answer 2

x × (y + z) = xy + xz

So here we have to verify if this formula is true.

x = $\frac{1}{2}$, y = $\frac{1}{3}$, z = $\frac{1}{5}$

$\frac{1}{2} * (\frac{1}{3} + \frac{1}{5}) = \frac{1}{2} * \frac{1}{3} + \frac{1}{2} * \frac{1}{5}$

$\frac{1}{2} * (\frac{5}{15} +\frac{3}{15} ) = \frac{1}{6} + \frac{1}{10}$

$\frac{1}{2} * \frac{8}{15} = \frac{5}{30} + \frac{3}{30}$

$\frac{8}{30} = \frac{8}{30}$

∴ x × (y + z) = xy + xz
