Sagot :
Bonjour,
4/4 + 8/6 = 1 + 8/6 = 6/6 + 8/6 = (8 + 6)/6 = 14/6 = 7/3.
2/4 + 4/1 = 2/4 + (4 * 4)/(1 * 4) = 2/4 + 16/4 = 18/4 = 9/2.
10/4 + 7/8 = (10 * 2)/(4 * 2) + 7/8 = 20/8 + 7/8 = 27/8.
Réponse :
7/3 ; 9/2 ; 27/8
Explications étape par étape
Bonsoir
Calculer les fractions suivantes et les réduire au maximum :
4/4 + 8/6
= 6/6 + 8/6
= (6 + 8)/6
= 14/6
= (2 x 7)/(2 x 3)
= 7/3
2/4 + 4/1
= 2/4 + (4 x 4)/(1 x 4)
= 2/4 + 16/4
= (2 + 16)/4
= 18/4
= (2 x 9)/(2 x 2)
= 9/2
10/4 + 7/8
= (10 x 2)/(4 x 2) + 7/8
= 20/8 + 7/8
= (20 + 7)/8
= 27/8
