(13-7+8)/9=14/9

Answer 2

Explicație pas cu pas:

Bună !!

•Rezolvarea:

**mai jos↓

$a) \frac{6}{8} + \frac{5}{8} + \frac{3}{8} = \frac{6 + 5 + 3}{8} = \frac{14}{8} ^{(2} = \frac{7}{4}$

$\frac{12}{100} - \frac{9}{100} + \frac{15}{100} = \frac{12 - 9 + 15}{100} = \frac{18}{100} ^{(2} = \frac{9}{50}$

$c) \frac{13}{9} - \frac{7}{9} + \frac{8}{9} = \frac{13 - 7 + 8}{9} = \frac{14}{9}$

Succes !!:)
