Sagot :
Bonjour
Simplifier les fractions suivantes :
a. 12/15 = (3 x 4) / (3 x 5) = 4/5
b. 45/35 = (5 x 9) / (5 x 7) = 9/7
c. 6/14 = (2 x 3) / (2 x 7) = 3/7
d. 90/40 = (10 x 9) /(10 x 4) = 9/4
e. 24/30 = (6 x 4) / (6 x 5) = 4/5.
Réponse:
a. 4/5 b. 9/7
c. 3/7
d. 9/4
e. 4/5
Explications étape par étape:
a. (3x4)/(5x3)
b. (9x5)/(7x5)
c. (3x2)/(7x2)
d. (9x10)/(4x10)
e. (4x6)/(6x5)
