Question

Calcule:5/9-3/9= e 1/2+2/3

Answer 1

$\frac{5}{9} - \frac{3}{9} = \frac{5-3}{9} = \frac{2}{9}$

$\frac{1}{2} + \frac{2}{3} = \frac{1+2}{6} = \frac{3}{6} =0,5$

Answer 2

Explicação passo-a-passo:

$a) \frac{5}{9} - \frac{3}{9} \\ \\ \frac{5 - 3}{9} \\ \\ \frac{2}{9} \\ \\ \\ \\ b) \frac{1}{2}+ \frac{2}{3} \\ \\ \frac{3 + 4}{6} \\ \\ \frac{7}{6}$
