bonsoir,

34/13 = 13/13 +13/13  + 8/13 = 2+8/13

62/13 = 13/13 +13/13+13/13+13/13 + 10/13 = 4 +1013

5/13 = 5/13

impossible

2 < 34/13 < 3

4 < 62/13 < 5

0 <  5/13 < 1

Bonsoir,

Exercice 3

a.

[tex] \frac{34}{13} = \frac{26 +8 }{13} = \frac{2 \times 13 +8 }{13} = 2 + \frac{8}{13} [/tex]

[tex] \frac{62}{13} = \frac{52 + 10}{13} = \frac{4 \times 13 + 10}{13} = 4 + \frac{10}{13} [/tex]

[tex]\frac{5}{13} = \frac{13 \times 0 + 5}{13} = 0 + \frac{5}{13} [/tex]

b.

[tex]2 < \frac{34}{13} < 3[/tex]

[tex]4 < \frac{62}{13} < 5[/tex]

[tex]0 < \frac{5}{13} < 1[/tex]

(exercice 4

a.

[tex]] \frac{78}{9} = \frac{72 + 6}{9} = \frac{8 \times 9 + 6}{9} = 8 + \frac{6}{9} = 8 + \frac{2}{3}[/tex]

b.

[tex] \frac{47}{5} = \frac{45 + 2}{5} = \frac{9 \times 5 + 2}{5} = 9 + \frac{2}{5} [/tex]

c.

[tex] \frac{96}{9} = \frac{90 + 6}{9} = \frac{10 \times 9 + 6}{9} = 10 + \frac{6}{9} = 10 + \frac{2}{3} [/tex]

d.

[tex] \frac{39}{5} = \frac{35 + 4}{5} = \frac{7 \times 5 + 4}{5} = 7 + \frac{4}{5} [/tex]

)

Bonne soirée.
