tolong Dibantu Dan dijawab dengan rumusnya

Bapak (b) = 12 hari
Paman (p) = 6 hari
Bersama-sama (x) = ?

[tex] \frac{1}{b} + \frac{1}{p} = \frac{1}{x} \\ \frac{1}{12} + \frac{1}{6} = \frac{1}{x} \\ \frac{1}{12} + \frac{2}{12} = \frac{1}{x} \\ \frac{3}{12} = \frac{1}{x} \\ \frac{x}{1} = \frac{12}{3} \\ x = 4[/tex]
