Bonjour, j’ai besoin d’aide

Calculer et simplifier les fractions suivantes:

A=2/3 - 5/4 (fraction)
B=4/5 + 3/10 (fraction)
C= 2/3 x 18/7 (fraction)
D= 2/5 - 3/6 +1/2 (fraction)

Merci

Bonjour,

A=2/3 - 5/4

= 8/12 - 10/12 = -2/12 = -1/6

B=4/5 + 3/10

=8/10 +3/10 = 11/10 = 1,1

C= 2/3 x 18/7  

= 36/ 21  = 12/7

D= 2/5 - 3/6 +1/2

=12/ 30  - 15/30 + 15/30

= 12/30 =  6/15 = 2/5
