Question

Efectuati: 1 spura 8 + 1 supra 9 + 1 supra 6​

Answer 1

8 = 2³

9 = 3²

6 = 2×3

cmmmc = 2³×3² = 8×9 = 72

⁹⁾1/8 + ⁸⁾1/9 + ¹²⁾1/6 =

= (9 + 8 + 12)/72

= 29/72

Answer 2

$\frac{1}{8} + \frac{1}{9} + \frac{1}{6} =$

$= \frac{54}{432} + \frac{48}{432} + \frac{72}{432} =$

$= \frac{174}{432} =$

$= \frac{29}{72}$
