Bonsoir

Écrire sous forme d’une fraction :

5 + 1/3

= (5 x 3)/(1 x 3) + 1/3

= 15/3 + 1/3

= 16/3

11 + 2/5

= (11 x 5)/(1 x 5) + 2/5

= 55/5 + 2/5

= 57/5

3 + 1/7

= (3 x 7)/(1 x 7) + 1/7

= 21/7 + 1/7

= 22/7

1 + 1/2

= (1 x 2)/(1 x 2) + 1/2

= 2/2 + 1/2

= 3/2

6 + 1/25

= (6 x 25)/(1 x 25) + 1/25

= 150/25 + 1/25

= 151/25

6 + 1/4

= (6 x 4)/(1 x 4) + 1/4

= 24/4 + 1/4

= 25/4
