Question

calcular K= 191919/919191+192192/273273+909/9191

Answer 1

Respuesta:

$= \frac{191919}{919191} + \frac{192192}{273273} + \frac{909}{9191} \\ = \frac{19(10101)}{91(10101)} + \frac{192(1001)}{273(1001)} + \frac{9(101)}{91(101)} \\ = \frac{19}{91} + \frac{192}{273} + \frac{9}{91} \\ = \frac{19}{91} + \frac{64}{91} + \frac{9}{91} \\ = \frac{92}{91} .$
