Answer 1

tu ai de aflat n-ul?
a) 7/9=n/27 => (27*7)/9=n => n= 21
b)n/14=3/2 => n= (3*14)/2=> n = 21
c) 48/n=6/10 => n=(48*10)/6 => n = 80
d) 80/50 = 8/n => n= (50*8)/80 => n = 5
e) 18/n = 3/4 => n= (18*4)/3 => n = 24
f) 1001/7777=13/n => n= (13*7777)/1001 => n= 101
g) 140/90=n/9 => n= (140*9)/90 => n= 14
h) n/11=48/44 => n= (48*11)/44 => n= 12
i) 101/37=505/n => n= (505*37)/101 => n= 185
j)5/6=n/30 => n= (30*5)/6=> n= 25
