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
