a/3=b/5=c/10  = k 
a = 3k
b = 5k 
c = 10k 

3k + 5k + 10k = 180 
18k = 180 
k = 180 : 18 
k = 10 

a = 3 x 10 = 30 
b = 5 x 10 = 50 
c = 10 x 10 =100 

30 + 50 + 100 = 180

a+b+c=180
a/3=b/5=c/10=k⇒ a=3k, b=5k, c=10k
3k+5k+10k=180
18k=180
k=180:18
k=10
a=3x10=30
b=5x10=50
c=10x10=100
Verific: 30+50+100=180
