determinați nr. "n" ştiind că urmatoarele propoziţii sunt adevarate : 6/5 = n/25 ,
n/12 = 4/6 , 24/n = 14/28 ,
60/40 = 9/n , n/3 = 48/n ,
4/n+1 = 24/30 , 2n+1/7 = 15/2,
3n-2/n =5/2 , n/n+1 = 12/15.​

Answer 1

Răspuns:

6/5=n/25=>n=30

n/12=4/6=>n=8

24/n=14/28=>n=48

60/40=9/n=>n=6

n/3=48/n=>n=12

4/n+1=24/30=>n=5

2n+1/7=15/2=>n=25.75

3n-2/n=5/2=>n=4

n/n+1=12/15=>n=4
