Răspuns :
a) Amplifici 5/3 cu 8 = 40/24
40 + 24 = 64 .
b) Amplifici 11/6 cu 7 = 77/42
77 - 42 = 35
40 + 24 = 64 .
b) Amplifici 11/6 cu 7 = 77/42
77 - 42 = 35
a) a/5=b/3=k
a=5k
b=3k
a+b=64
5k+3k=64
8k=64
k=8
a=5x8
a=40
b=3x8
b=24
b) a/11=6/6=k
a=11k
b=6k
a-b=35
11k-6k=35
5k=35
k=7
a=11x7
a=77
b=6x7
b=42
