Bonjour pouvez-vous m’aider merci exercice 6

exercice 6
1: A. 100= 2x2x5x5
B. 24= 2x2x2x3
C. 30= 2x3x5
D. 44= 2x2x11

2: A. 30/24 = (2x3x5) / (2x2x2x3) = 5/4
B. 30/100 = (2x3x5) / (2x2x5x5) = 3/ 10
C. 24/44 = (2x2x2x3) / (2x2x11) = 6/11
D. 44/100 = (2x2x2x3) / (2 x 2 x 5 x 5) = 6/ 25

bonsoir

100=2*2*5*5
24=2*2*2*3
30=2*5*3
44=2*2*11

30/24=2*5*3/2*2*2*3=5/2*2=5/4
30/100=2*5*3/2*2*5*5=3/2*5=3/10
24/44=2*2*2*3/2*2*11=2*3/11=6/11
44/100=2*2*11/2*2*5*5=11/5*5=11/25
