Answer 1

$\frac{a}{\frac{9}{3} } =\frac{b}{\frac{1}{2} } =\frac{c}{\frac{10}{12} }$

a/3=2b=6c/5

b/6=c/10=a/3=k

a=3k        b=6k        c=10k

a+b+c=106

19k=106

k=6,1

a=18,3

b=36.6

c=61

3.a/2=b/3=k          a=2k         b=3k

5k=360    k=72

a=144       b=216

4.x/6=y/4=k

(x,y)=30   x=30t       y=30 d   (t,d)=1

x=6k      y=4k
