Efectuatu scaderule 14 supra 37 minus 9 supra37,7supra9 minus4 supra 27,11supra6minus13supra9

Answer 1

$\frac{14}{37} - \frac{9}{37 } = \frac{14 - 9}{37} = \frac{5}{37}$
$\frac{7}{9} - \frac{4}{27} = \frac{21 - 4}{27} = \frac{17}{27}$
$\frac{11}{6} - \frac{13}{9} = \frac{33 - 26}{18} = \frac{7}{18}$
