Sagot :
[tex]c = \frac{5}{9} + \frac{1}{3} [/tex]
[tex]c = \frac{5 \times 3 + 9 \times 1}{9 \times 3} [/tex]
[tex]c = \frac{15 + 9}{27} [/tex]
[tex]c = \frac{27}{24} [/tex]
[tex]c = \frac{8}{9} [/tex]
Réponse :
Calculons la fraction
C = 5/9 +1/3
[tex]C = \frac{5}{9} + \frac{1}{3}\\C = \frac{15+9}{27}\\ C = \frac{24}{27}\\ C = \frac{8}{9}[/tex]
